Explosion proof RTD sensors
Explosion Proof RTD sensors are for use in hazardous areas. They are designed to extinguish flames inside the device eliminating the potential for ignition of ammable mixtures in the surrounding atmosphere. FM and CSA approved assemblies, dependent on connection head type, meet XP Class I, Division 1, Group A, B, C and D; DIP Class II, Division I, Groups E, F, G, and Class III, Division 1. They may be installed directly in the process without being inserted into a thermowell. The assemblies feature 316 stainless steel sheaths in various diameter sizes. They are available with or without process mountings and with aluminum or stainless steel explosion proof connection heads.
​
Explosion proof RTD sensors is a kind of temperature sensor, which is widely used in chemical industry automatic control system. Through the temperature sensor, the temperature parameter of the controlled object can be turned into an electrical signal, which can be transmitted to the display, record and regulator to perform detection, Regulation and control. In chemical plants, the production site is often accompanied by various flammable and explosive chemical gases and steam. It is very unsafe to use ordinary RTD sensors, and it is very easy to cause environmental gas explosions
Types of explosion proof RTD sensors
Industrial assembly type
The product is available in the range of Flameproof Protection Head, Flameproof Stainless Steel Protection Head,Adjustable Connection, and with Fix Connection.The following may be specified at time of order: sensor type; fixed, replaceable or mineral insulated construction; accuracy class; diameter; insertion and lagging lengths; process fittings and optional head-mount transmitter.
Explosion proof MI RTD sensor probe
The mineral insulated RTD sensor probes are manufactured with compacted magnesium oxide (MgO) insulation housed in a stainless steel or alloy sheath that protects the thermocouple element from the application's environment. This construction provides an incredibly durable temperature sensor that can be adapted to a wide variety of applications. Operating temperatures -100 to 500 ° C. Special mineral insulation protects thermocouple from moisture and thermal shock and permits operation in high temperature and high pressure environments The product is available in the range of Flameproof Protection Head, Flameproof Stainless Steel Protection Head,Adjustable Connection, and with Fix Connection
