Solvent Vapors Detector-Transmitter
- Highly sensitive Photo Ionization Detector
- Range 0...40 or 0...200 ppm isobutylene
- Resolution 1 ppb or 1 ppm isobutylene
- Two SPST relays option
- 2 × 4-20 mA or 0-10 V, RS485
Volatile organic compounds transmitter E2638-PID is a member of new PluraSens® family of multifunctional measurement instruments.
The instrument utilises highly sensitive photoionization detectors (PID) with extremely low minimal detection levels. The transmitter exhibits sensitivity to compounds with ionization potential less than 10.6 eV, i.e. to most solvent vapors.
Two relays with closing contact (optional) may be used for remote signalling or concentration control. Two alarm set-points are user settable.
Two analog outputs and RS485 digital interface with industry standard Modbus RTU protocol can be used to connect the detector to safety or building automation systems.
