Its design goal is to meet the detection requirements of toxic, flammable gases and oxygen in the semiconductor and other manufacturing industries, suitable for non explosive environments in indoor safe areas.

The overall architecture of the equipment consists of four core components: the main module, installation bracket assembly, sensor box, and pump module. This modular design not only facilitates installation and maintenance, but also allows for flexible configuration according to different detection requirements. The user interface includes a backlit LCD display screen, LED indicator lights, and a four key operation keyboard, which can intuitively display information such as gas concentration and alarm status, and support parameter settings and functional operations.

In terms of communication and power supply, Midas-M has high flexibility, supporting 3 onboard relays, 0-21mA analog output, Modbus/TCP digital communication, and Power over Ethernet (PoE). It can achieve the integration of power, control, and data transmission through a single Ethernet connection, greatly simplifying system wiring.

Installation process and technical specifications

（1） Mechanical installation details

Transmitter installation: Adopting a step-by-step installation strategy, first fix the installation bracket, and then install the main module. The specific steps are: remove the equipment door → loosen the fixing screws → pull out the main module → drill holes according to the template (hole spacing 55.9mm) → fix the bracket with M4 screws → align the main module with the bracket’s rounded corner positioning → horizontally push in the main module to fully connect the connector and pipeline → tighten the bottom fixing screws. Special attention should be paid to removing the internal packaging card of the fixed pump, otherwise it may cause equipment damage.

Relay module installation: independent of the main module installation, the steps include: removing 4 screws and cover plate → positioning the module on the pre installed screws and tightening it → threading and connecting to the terminal block → resetting the cover plate and screws → docking the module connector → fixing the bracket and module with special screws.

（2） Fluid system configuration

Sampling and exhaust pipeline parameters:

Inlet sampling: the maximum length is 30m (100ft), the vacuum degree at the sampling point is ≤ -25.4cm H ₂ O. It is recommended to use a 1/8-inch ID thick wall Teflon FEP tube, the flow is stable at 600cc/min, and different pipe diameters correspond to different transmission times (25 seconds for 1/8-inch ID, 53 seconds for 3/16 inch ID).

Export exhaust: maximum length 30m (100ft), back pressure ≤ 20.3cm H ₂ O, pipeline specification 4.76mm ID × 6.35mm OD.

Pipeline preparation and filtration: The pipeline needs to be vertically cut and deburred, and the depth of insertion into the equipment port should be 15.5mm (marked for confirmation). External filters must be used: 780248 for ordinary gases and 1830-0055 or 1991-0147 for corrosive gases. It is recommended to replace them every 3 months.

（3） Electrical Connection Specification

Power requirements: Supports 24VDC discrete power supply or 48VDC PoE power supply (IEEE 802.3af standard), both cannot be connected simultaneously. Maximum power consumption: Under normal operating conditions, it is about 5W, and at full load (4-channel alarm+maximum pipeline load), it is ≤ 11.45W.

Terminal definition and wiring: The terminal supports 24-14 AWG wires (recommended 16 AWG), including interfaces for power supply, 4-20mA output, relays, etc. Among them, the 4-20mA output can be configured as a 3-wire source type, 3-wire drain type, or 4-wire isolation type. When wiring, attention should be paid to the switch settings (INT/NEXT).

Grounding requirements: If the metal casing of the equipment is not directly connected to the grounded metal surface, a dedicated grounding terminal must be connected to the external grounding electrode through PG16 glass; When using PoE, shielded CAT5 cables should be used to avoid interference from grounding loops.

（4） Installation of sensor box

The sensor box supports plug and play, and it is necessary to confirm that the model matches the detected gas before installation. The steps are: power off → open the door → remove the BiAS battery module and plug cap → align the sensor box pins and slots → gently push until fully engaged → close the door → press the “O” key to clear the “Detect New Cartridge” prompt → confirm that the green light is flashing, the yellow/red light is off, and the displayed concentration is zero.

（2） Calibration and maintenance functions

Calibration process:

Zero point calibration: It needs to be performed in an environment without target gas, and confirmed after the reading stabilizes. It is suitable for sensors other than O ₂.

Range calibration: Introduce a known concentration standard gas and confirm after the reading stabilizes. The O ₂ sensor is calibrated with 20.9% air as the calibration point.

Flow calibration: Adjust the pump speed to stabilize the flow at 600cc/min, and recalibrate after replacing the pump or filter.

Bump Test: A functional test to verify the responsiveness of sensors. The steps are: enter test mode → enable collision testing → introduce test gas → confirm alarm triggering → reset ventilation. It is recommended to use target gas or cross sensitive gas (such as O3 can be replaced by NO ₂) every 6 months.

Pyrolysis module XT electrochemical cell gas detection sensor

Including hexafluoro-1,3-butadiene (C ₄ F ₆), octafluorocyclopentene (C ₅ F ₈), etc., each substance corresponds to a specific sensor model and nominal range.

Working principle of sensors

Electrochemical sensors are all ampere type, similar to fuel cells. In order to generate current, they lack a component, which is the gas (target gas) that should be detected. The target gas diffuses through the breathable membrane into the sensor, where an electrochemical reaction occurs, producing a low current proportional to the measured gas concentration (usually read in nA/ppm).

The current is amplified into a signal and processed by electronic circuits to display real-time gas concentration. The zero current of electrochemical cells always exists and is monitored and suppressed by electronic devices.

Honeywell Analytical Instruments has created an “intelligent sensor” with a built-in PROM that programs all relevant sensor data (such as sensitivity, target gas, first calibration date, calibration data, zero current, and alarm level) onto the chip. The detector can read this data and automatically adjust the amplification factor.

Sensor self-test

All relevant sensor data is programmed into the PROM inside the electrochemical sensor, and the detector can read this data. Perform an automatic sensor self-test every 24 hours, comparing the electronically activated sensor signal with the stored calibration curve to ensure that the sensor remains within the specifications set during the initial calibration. If the sensor exceeds the specifications, the instrument will indicate that the sensor needs to be checked or replaced.
