- Toxic Gas Transmitter/Sensors
- The CTS-M5 Series is a microprocessor based transmitter
- It uses an Electrochemical gas sensor to detect a variety of gases
- Typical applications are enclosed parking facilities, refrigeration rooms and oxygen storage rooms
- QEL Engineers, through extensive research and development, have designed the M5 to be an industry leader in performance and application
- The M5 offers good value. Standard features within the M5 can only be found as expensive options in other manufacturers’ product
- A digital display (LCD), push-button programming and on-board meter jacks are all standard
- The transmitter provides an analog output of 4-20 mA DC or 2-10 VDC, linear to the measured gas range, for transmission to the Building Automation System (BAS) or controller supplied by others
- The signal is fully user assignable over the gas range and can be configured for rising or falling gas concentration
- In addition, the RS-485 communications is built in Input voltages of 24 VDC or 24 VAC with wide tolerances are acceptable
- Relay setpoints may be seen as increasing or decreasing actuation simply by adjusting the deadband relationship
- Set the deactuation point above the actuation setpoint and the M5 will automatically alarm on decreasing concentrations
- Relay setpoints are always present even though the relays themselves are an option
- Calibration is very easy – simply apply the calibration gas and adjust the potentiometer to the desired reading on the display
- The standard enclosure is a fire retardant Polycarbonate/ABS blend
