Acetic acid gas detector for online, continuous detection of acetic acid vapour presence or LEL level in ambient air or ducts. The detector is explosion proof ATEX certified with SIL 2 safety level and suitable for installation in hazardous area Zone 1 and Zone 2. The instrument can be installed at solvent storage facility, paint booth, refinery, paint manufacturing units, cleansing facility at textile manufacturing etc.
It is available with LCD Display, on-board relay contacts, flashing alarm LEDs, auto diagnostic watch dog, non-intrusive calibration, with industry standard linear analog output.
SMART MSR-Sensitron series acetic acid gas or vapour sensor is highly robust, industrial grade, flameproof or explosion proof instrument for LEL concentration detection. The instrument can be installed for flammability level or LEL detection of acetic acid gas in all industrial and commercial area eg. chemical plant, fertilizer, solvent manufacturing unit, printing press, paint booth etc
The detector can be installed at walls, surfaces or in ducts for monitoring in gas or air sample. It is ATEX EEx’d’ certified with SIL 2 safety integrity level for hazardous area installation Zone 1 and 2.
The sensor transmitter offers linear, proportional analog output in industry standard current signals, over measuring a range of 0 ~ 100 % LEL (lower explosive limit). The detector works on highly sensitive catalytic bead-based pellistor sensor cell, with low response time. It has unique feature of an auto diagnostic watchdog with zero point tracking feature. Due to its 10-bit microprocessor based control unit, it offers high accuracy over the long term. The detector is also equipped with a sintered filter with flashback arrestor for enhanced safety.
