Product Overview

1. Core purpose and design objectives

The 330400 and 330425 acceleration sensors are designed specifically for measuring the acceleration of critical machinery casings, especially suitable for scenarios such as gear meshing monitoring. Both comply with the American Petroleum Institute API 670 standard, with the main differences being range and sensitivity:

330425: Larger range (75 g peak), sensitivity of 25 mV/g, suitable for high vibration intensity scenarios.

2. Application precautions

The sensor needs to be installed on the bearing seat or casing to ensure that the rotor vibration can be effectively transmitted to the installation position, otherwise it may cause measurement signal attenuation or distortion.

Improper installation can affect amplitude and frequency response. It is recommended to refer to the accompanying manual and application guide, and if necessary, apply for Bently Nevada’s engineering services to determine the best installation solution.

Acceleration range: 490 m/s ² (50 g) peak, only valid within the frequency range of 10 Hz-15 kHz; A frequency above 15 kHz (especially the resonance point) will significantly reduce the range/735 m/s ² (75 g) peak, and the range limit is consistent with 330400

Amplitude linearity: ± 1% (when acceleration ≤ 490 m/s ² peak)/± 1% (when acceleration ≤ 735 m/s ² peak)

Broadband noise base: 0.039 m/s ² (0.004 g) rms, frequency range 10 Hz-15 kHz/unspecified, performance consistent with 330400 within the same frequency band

Frequency response: -10 Hz-15 kHz: ± 3 dB/-30 Hz-10 kHz: ± 10%

(Ensure accurate capture of vibration signals within a wide frequency range)/Completely consistent with 330400

Temperature sensitivity: typical value -11% to+3% (the rate of change of sensitivity with temperature within the operating temperature range)/completely consistent with 330400

Lateral sensitivity:<5% (relative to axial sensitivity, reducing the impact of installation angle errors on measurement)/completely consistent with 330400

Installation resonance frequency:>30 kHz (to avoid interference from resonance on high-frequency vibration measurement)/completely consistent with 330400

Power requirements: – Input voltage: -24 ± 0.5 Vdc

-Bias current: 2 mA (nominal)/exactly consistent with 330400

Output bias voltage: -8.5 ± 0.5 Vdc (reference voltage relative to ground)/completely consistent with 330400

Grounding design: shell isolation (to avoid interference with measurement signals caused by grounding loops)/completely consistent with 330400

Environmental adaptability parameters

1、 Temperature range

Working and storage temperature

Range: -55 ° C to+121 ° C (-67 ° F to+250 ° F)

Explanation: The sensor can work stably in extreme high and low temperature environments, suitable for high temperature equipment such as industrial furnaces and steam turbines, or cold outdoor scenes. It can also withstand this temperature range during storage without the need for additional temperature control protection.

2、 Impact bearing capacity

Impact limit

Peak value: 49050 m/s ² (5000 g)

Description: It can withstand severe mechanical impacts (such as accidental collisions during installation, instantaneous impacts during equipment start-up/shutdown), ensure that internal components are not damaged, and is suitable for heavy industrial environments with severe vibrations (such as mining machinery and stamping equipment).

3、 Humidity and protective performance

relative humidity

Tolerance range: 100% condensation (non submerged state)

Protection design: The sensor housing is sealed tightly and made of 316L stainless steel material, which can prevent water vapor and dust from entering the internal circuit. It is suitable for humid workshops, outdoor rainy and snowy environments, or high humidity process flows (such as papermaking and food processing).

IP rating

Equivalent protection: IP68 (dustproof and waterproof)

Note: This level is only applicable to the sensor body, and the cable part needs to be separately protected to avoid water ingress or wear.

4、 Magnetic field anti-interference ability

Magnetic field sensitivity

Limit value:<2.21 mm/s ²/Gauss (225 mg/Gauss), test conditions are 50 Gauss, 50-60Hz magnetic field

Explanation: In strong electromagnetic environments (such as near motors and transformers), it is less affected by magnetic field interference, ensuring the accuracy of vibration measurement data and reducing false signals.

5、 Base strain sensitivity

Regarding the differences in different serial numbers

The serial number starts with “G” (produced after April 2004): 49 mm/s ²/mstrain (0.005 g/mtrain), and the influence of substrate strain on measurement is minimal, so there is no need to install an additional base.

Serial number without “G” (produced before April 2004):

When there is no installation base: 980 mm/s ²/mstrain (0.100 g/mtrain), with high strain sensitivity, it needs to be used in conjunction with a dedicated installation base.

When equipped with a mounting base: 4.9 mm/s ²/mstrain (0.0005 g/mtrain), it can effectively reduce substrate strain interference.

Product Overview

Core functions

The 330500 Velomitor piezoelectric velocity sensor is a special type of piezoelectric accelerometer that uses solid-state design and integrates embedded electronic components for measuring absolute vibration (relative to free space) of bearing seats, housings, or structures. It has no moving parts, avoiding mechanical degradation and wear, and can be installed vertically, horizontally, or at any angle.

Application points

Suitable for detecting vibration changes caused by common faults such as rotor imbalance and misalignment.

If the integral output is used to measure displacement, it should be noted that electrical noise may amplify and affect data accuracy. Therefore, it is necessary to choose the installation position, grounding, and shielding method reasonably to maximize amplitude and frequency response and reduce non actual vibration data interference.

Product Overview

Core functions

The 515 lockout and testing module is a specialized testing device for GE Multilin relays, with main functions including:

Provide trip locking, relay isolation, and testing functions;

By turning on the switch and inserting the test plug, it is possible to monitor the phase current and residual current from the primary CT, or inject current into the relay through the secondary injection testing equipment during debugging;

Ensure that the CT (current transformer) is short circuited during testing to avoid high voltage hazards, while also isolating the output circuit of the trip relay to prevent false tripping.

main features 

Including a 14 pole switch group, the CT input automatically short circuits when the current switch is turned on;

Support injection of current in each phase, equipped with grounding terminals;

Intuitively isolate (disconnect) the output circuit of the trip relay and provide a protective cover;

Suitable for power and industrial scenarios, equipped with 515 test plugs.

Installation instructions

CT Connection and Safety Requirements

The module provides a short-circuit switch for connecting three-phase CTs and individual zero sequence ground fault CTs (or three-phase CTs used for residual ground fault detection);

Key safety point: The CT must be connected to the short-circuit side of the switch. When the CT switch is opened, the CT will be short circuited to avoid dangerous high voltage caused by CT open circuit.

PANEL MOUNT

The module consists of a metal chassis and a test switch, and needs to be installed by sliding it in from the front of the panel;

The panel needs to be cut according to the dimensions shown in Figure 3, and the module should be fastened by bending retaining tabs. If necessary, the accompanying # 8 screws and anti vibration nuts can be used for reinforcement;

After installation, fasten the front cover and rotate the fasteners at both ends by 1/4 turn to lock it in place;

There is a grounding screw at the bottom right corner of the module’s rear side, which needs to be connected to the panel chassis grounding.

Operating instructions

Switch configuration and function

There are a total of 14 switches, divided into two categories:

6 single pole switches (terminals 1-6 and 15-20): used to isolate relay output circuits, disconnect trip and auxiliary circuits, and achieve trip locking;

4 sets of dual switches (terminals 7-14 and 21-28): corresponding to A-phase, B-phase, C-phase currents and grounding currents, each set of switches is used for CT short circuit, test current injection, and CT current measurement.

The working logic of each set of dual switches:

The first switch (such as terminals 7 and 21): regardless of the switch status, the terminals are always short circuited;

The second switch (such as terminals 8 and 22) adopts a “close first, then open” design. When closed, the terminals are short circuited, and when opened, terminals 8-22 are open and 22 and 7-21 are short circuited (to achieve CT short circuit).

test process

Before testing: Disconnect the trip and auxiliary circuits to prevent accidental tripping, and then short-circuit the CT;

During testing: After turning on the switch, insert the test plug to inject signals or monitor CT current;

After testing: first close the CT switch to restore the normal operation of the relay, and then close the trip and auxiliary circuits.
