Crowcon IR Plus with IS Barrier Module | IR Detector, IS Barrier | Dual IR, T90 4 s, SIL2, 4.9kg
Supplied with an intrinsically safe barrier module (4.9 kg in total), this IR Plus configuration connects to a remote display or remote access box over a 1.5 m or 3 m cable. That allows non-intrusive testing and monitoring of detectors in hard-to-reach positions while retaining the 4-second dual-waveband infrared measurement.
Key features
- Dual IR waveband measurement
- Heated optics with Stay-ClIR hydrophobic mirror
- Remote non-intrusive testing options
- Wall, pipe, duct or junction box mounting
- Serviceable optics; mirror cleaning kit available
- 4-20 mA and RS-485 Modbus as standard, with HART 7 as an option
