The Detcon model TP-624D 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-624D 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 cal port. The packaging is Explosion Proof (Class I, Division 1, Groups B, C, D).
Equipped with a standard analogue 4-20 mA current signal equivalent to the sensor range of detection, RS-485 serial communications port, one-person remote calibration, self-adjusting zero and span, and LED indicators for two alarm relays and one fault relay and calibration status.
Features
- cCSAus approved for Class I, Division 1, Groups B, C, & D Transmitter design fits all existing Detcon MOS H2S sensors dating back 20 years.
- Compatible with PLCs, SCADA, DCS, via 0-20 mA, and/or RS-485, and/or alarm relays.
- Sensor status and parameters are accessible via RS-485 (Modbus).
- Menu programmable relays standard (two alarms plus fault).
- Simple menu-driven calibration- less than 3 minutes.
- LED display and LED indicators for FAULT and CAL status.
- Plug-in field-replaceable transmitter.
- Response similar to electrochemical sensor: T50 <30sec., T80 <60 sec.
- Direct response constant temperature control.
- Withstands exposure to high-range concentrations of H2S and other acid gases.
- Impervious to high moisture environments in both powered and non-powered modes.
- Extensive Fault diagnostics.
- Replaces model TP-624C.
Applications
- Oil and Gas Drilling Rigs
- Oil and Gas Production Sites
- Refining and Petrochemical
- Pulp and Paper Mills
- Waste Water Treatment Plants
