ATEX temperature sensors

For temperature measurement in risk areas, choose your ATEX sensor. 

What is an ATEX temperature sensor?

To perform temperature measurements, you need a high-precision device. Especially in risky environments where there is little room for error. It is precisely for this reason that at Guilcor, we offer you a selection of ATEX sensors with precise temperature control.

Specifications of ATEX measuring devices

Our ATEX wired and connection head temperature sensors are characterized by proven quality.  

Regardless of the model chosen, here are the characteristics of these temperature control devices: 

  • availability with different cable lengths, diameters and tube lengths; 
  • indoor and outdoor use; 
  • an IP66 (against dust and water jets) and IP67 (dustproof and resistant to temporary immersion at a depth of 1 meter) protection index; 
  • ATEX certification for use in potentially explosive environments.

The ATEX standard

Our measurement probes are ATEX certified. This means that they meet the requirements of the European standard relating to products usable in EXplosive ATmospheres. This standard sets safety rules for hazardous areas; either which are directly in contact with gas (this is zone 1), or which are close to the gas (this is zone 2). 

With EX marking, our thermal measuring instruments and their accessories (thermowell, bayonet, cables, etc.) are protected against the risk of explosion, thus fully complying with the European ATEX standard. 

What are ATEX temperature probes used for?

ATEX temperature sensors mainly concern industrial applications. 

In concrete terms, the use of an ATEX sensor makes it possible to measure the temperatures in air conditioning or ventilation ducts. They will be able to give you the exact contact temperature (in degrees celsius or fahrenheit) of the objects to be studied. But they will also tell you about any significant temperature variations. 

Our thermometers and measuring probes work on the principle of definite dependence of the change in sensor property and the change in surface temperature. 

Temperature detectors are designed to operate in a chemically non-aggressive environment. Its use must be chosen according to the temperature and chemical resistance of the housing, as well as the power cable.

Finally, they are not able to generate sparks

How to test your measuring device?

To ensure that your measuring instrument is working correctly (and above all that the measured temperature is correct), there are two methods: 

Cooling: here, it involves placing your ATEX temperature sensor in a glass of ice water. Leave it for about fifteen seconds and check the displayed temperature. If it is zero, your sensor is working properly. 

Heat: Conversely, you can control the temperature using heat. But here you have to use an online calculator to know the exact water temperature. Once you know this measure, start by boiling water. As soon as the water is boiling, insert the measuring probe and stir for about ten seconds. It should show a high temperature. And if the sensor really works, the previously calculated measurement should appear.  

Where to find your ATEX temperature probe?

To measure the ambient temperature in a hazardous area, you will need an ATEX temperature probe. You will then find all the models at Guilcor (humidity transmitter, resistance thermometer, thermocouple probe, etc.) with specific characteristics (with display, stainless steel connector, precise measurement, variable temperature range depending on the model, cable length made to measure, with or without cable, low or high temperatures, etc.). 

Once you have found the equipment that meets your needs, Guilcor ships your package to over a hundred countries around the world. And if needed, you can also benefit from express delivery.
