Sensor transmitter accepts toxic, oxygen modules



Sensor transmitter from Global Detection Systems Corp. features field replaceable toxic/oxygen sensor module.

Model GDS-49 sensor transmitter from Global Detection Systems Corp. accepts toxic or oxygen electrochemical sensor modules and functions in a 2-wire 4-20 mA “sink” mode to transmit gas values to an appropriate receiver. Device reportedly overcomes noise immunity problems associated with electrochemical sensors by enclosing its plug-in sensor module in a rugged metallic enclosure. Approvals include CSA Div. 1 & 2 explosion-proof and intrinsically safe (IS) with an approved IS barrier.

Sensor elements are interchangeable with the vendor’s other smart sensors to reduce spare sensor inventory. Missing or defective sensors may be detected and flagged by transmitting a value of less than 2 mA to the receiver. Also available are 1-, 2-, 8-, and 16-channel receivers suitable for calibration, display, alarm, and transmission of monitored gas valves.
