Oldham Simtronics DG-TT7-S Solid-State (MOS) Gas Detector
The MultiTox DG-TT7-S is a solid state (MOS) based smart gas detector for the detection of Hydrogen Sulphide. The device has been designed to withstand harsh environment and provide easy operation The unit is fully configurable using a wireless hand-held terminal TLU, using a magnet or by using HART protocol option. The configuration of the outputs is adjustable using the TLU or the magnet that can be used in areas classified as potentially explosive. The MultiTox DG-TT7-S is SIL2 certified, 3 on board relays in option, plug and play sensors and a high visible display that changes colour depending on the status mode. The unit may be interfaced directly with a wide range of centrals and PLC’s. The device supports HART 7 protocol option for full configuration and diagnostics over non-proprietary interface. This new version also offers automatic calibration, TELECAPTEUR Calibration Management Software. It allows loading, comparison and logging of the last calibrations carried out and this can be done by one person only.

Teledyne Detcon IR-700-CH Combustible Gas Sensor
Model IR-700-CH is a non-intrusive “Smart” sensor designed to detect and monitor combustible hydrocarbon gases in air over the range of 0-100% LEL using miniature non-dispersive Infrared Optical (NDIR) sensor technology. As compared to catalytic bead sensors, with NDIR there is no risk of sensor poisoning, no risk of high concentration saturation, and no need for O2 to be present. The plug-in, field replaceable detector features over-sized gold-plated connections that help prevent corrosion. The IR-700-CH’s rugged framework includes an electro-polished 316 stainless steel housing with fully encapsulated electronics and dual layer surge protection. This innovative design virtually eliminates sensor failure due to water ingress, corrosion, vibration, and transient spikes. A primary feature of the Model IR-700-CH is embedded intuitive software that simplifies operator interface by guiding the user through routine calibration, configuration, and fault diagnostic functions using a built-in alpha/numeric display. The Model IR-700-CH is equipped with standard analog 4-20mA, and Modbus™ RS-485 outputs. Among its unique features is a wireless option that can be used with Detcon’s SmartWireless® product line. Additional integration options include a Remote Alarm Module (RAM) and HART. Detcon’s combustible gas sensor has an infinite shelf life and is supported by a 5-year warranty.

Oldham Simtronics CTX 300 Fixed Toxic Gas Detector
Presentation The CTX 300 can detect O2, CO2, toxic and refrigerant gases. TELEDYNE Gas & Flame Detection offers a detector version with a wide range of sensors (infrared, electrochemical, semiconductor) according to your application needs. It is also available with or without display. Simplicity Sensor replacement does not require any special menu access. Just replace the sensor without even powering down the transmitter! Reduced maintenance As the only consumable element, the CTX 300 sensor is easily replaceable. New sensors come pre-calibrated from the factory.
