The explosion proof sensor and housing are ideal for hazardous area monitoring and meet NEC requirements for Class I, Division I, Group A-B-C-D. All the models can provide either 4-20mA or 0-1 VDC output for data acquisition purpose, and PLC interfacing. Analog meter indicateds PPM or % LEL. Digital meter use large Red LED is also available.
Each detector includes sensor and controller (R-type includes housing and 50 feet cable wire). Standard model includes meter (ppm or % LEL), LED alarm, audio alarm, fail alarm, check and test switches and relay contacts.
