TP-624D Hydrogen Sulfide Sensor
Manufacturer: Teledyne| DetconDetcon Model TP-624D is a “Smart” gas detection sensor designed to detect and monitor H2S in air over the range of 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 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, Div. 1 Groups B, C, D).
Model TP-624D is equipped with a standard Analog 4-20 mA current signal equivalent to the sensor range of detection, RS-485 serial communications port, 3 alarm relays, one-man remote calibration, self-adjusting zero and span, and LED indicators for fault, alarm, and calibration status.
Detcon’s solid state MOS sensor has an infinite shelf life and is supported by an industry leading 10-year conditional warranty.
