The Detcon model TP-524D by Teledyne is a “Smart” gas detection sensor designed to detect and monitor H2S in the air over the ranges of 0-20 ppm, 0-50 ppm, and 0-100 ppm using a proprietary solid-state metal oxide semiconductor technology.

This innovative design offers several advantages, including longer sensor life and better temperature and humidity performance. Model TP-524D features Detcon’s MicroSafe intelligent electronics, non-intrusive operator interface and comprehensive fault diagnostics.

The sensor transmitter features an advanced universal design that fits all existing Detcon MOS H2S sensors dating back more than 20 years. The sensor assembly includes a MOS detector in a stainless steel housing, a base connector board, an explosion-proof enclosure (available in aluminium or stainless steel), a plug-in control transmitter circuit, and a splashguard with an integral calibration port. The packaging is Explosion Proof (Class I, Division 1, Groups B, C, D).

Model TP-524D is equipped with a standard analogue 4-20 mA current signal equivalent to the sensor range of detection, self-adjusting zero and span, and LED indicators for fault and calibration status. A HART communications option is also available. An industry-leading 10-year conditional warranty supports Detcon’s solid-state MOS sensor.
