Fixed Gas Detector with Remote Sensor

Features

Fixed Gas Detector with Remote Sensor is actually the same as the online gas detector (fixed gas detector). It’s just that the connection method of the detector is slightly different. Sino-Inst can extend the sensor part of the gas detector according to the needs of the user, so it is convenient to install and use in different locations.

If it is a high-temperature gas detector, the sensor part of the detector and the circuit board connection part use a high-temperature resistant cable, so there is no need to worry about circuit damage.

Advantages include:

• The display and the detection sensor probe are separate. The sensor head can be placed in a difficult-to-reach or dangerous location, and the operator can monitor the gas concentration at a safe distance.
• If the sensor needs to be replaced or calibrated, only the sensor head needs to be handled without moving the entire device.
• It also has functions such as on-site data display, explosion-proof sound and light alarm, detection concentration signal conversion and transmission, and relay output control.
• It can provide 4-20mA standard signal, RS485 signal, voltage signal, and switch signal. It is convenient to connect with various control alarms, PLC, DCS and other control systems to realize remote monitoring and data transmission.
• It can be operated by buttons or infrared remote control according to actual needs;
• The display control unit usually has multiple functions. Such as data recording, alarm setting, display of gas concentration, etc.
• Sensor expiration, over-concentration alarm, over-temperature alarm, fault alarm, instrument calibration reminder function, etc.;
• For certain environmental applications, the instrument can realize zero point automatic correction function;
• It can be customized with temperature, humidity detection and display.

Oxygen detectors are widely used in industrial production safety, laboratories, environmental monitoring and other fields. Especially in limited space operations, confined environments, high-altitude operations and other occasions. It is of great significance to ensure personnel safety.
