Detcon The TP-524D is a "smart" gas detection sensor designed to detect and monitor H2S in air over a range of 0 to 100 ppm using patented solid metal oxide semiconductor technology.
This innovative design offers several benefits, including longer sensor life and better temperature and humidity performance.
The TP-524D is equipped with Detcon's MicroSafe ™ intelligent electronics, non-intrusive operator interface and comprehensive fault diagnosis. The sensor transmitter has an advanced universal design that fits all existing Detos MOS H2S detectors over 20 years old.
The sensor assembly includes a MOS sensor in a stainless steel housing, a basic connection board, an explosion-proof enclosure (available in aluminum or stainless steel), a pluggable control emitter circuit and a splashguard with integrated gauge port. The packaging is explosion-proof (Class I, Division 1, Groups B, C, D).
The TP-524D is equipped with a standard 4-20 mA analog current signal equivalent to the auto-adjustable sensor detection range, zero and range, and LED indicators for fault and signal conditions. 'calibration.
A HART communication option is also available. Detcon's Solid State MOS Sensor has an infinite life and is backed by a 10-year industry leading conditional warranty
