MicroSafe TP-624 D

Model TP-624D is a “Smart” gas detection sensor designed to detect and moni- tor H2S in air over the ranges of 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-624D features Detcon’s MicroSafeTM intelligent electronics, non-intru- sive operator interface and comprehensive fault diagnostics. The sensor transmit- ter 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 stainless steel housing, a base connector board, an explosion proof enclosure (available in aluminum or stainless steel), a plug-in control transmitter circuit, and a splashguard with integral cal port. The packaging is Explosion Proof (Class I, Division 1, Groups B, C, D).

Model TP-624D is equiped with a standard analog 4-20 mA current signal equivalent to the sensor range of detection, RS-485 serial communications port, , one-man remote calibration, self-adjusting zero and span, and LED indicators for 2 alarm relays and 1 fault relay and calibration status. Detcon’s solid state MOS sensor is supported by an industry leading 10-year conditional warranty.
