About Choosing a Heater

Humidity and Temperature Transmitters


These sensors measure temperature and humidity, then send that information to your PLC or controller to regulate heating and cooling equipment, alarms, and data recorders. Choose a sensor that works with your digital IO-Link or analog 4-20 mA system. Clip it to a DIN rail or mount it to a surface, and use the micro M12 plug to connect the sensor to your controller. These sensors are often installed in enclosures.
Sensors meet American, Canadian, and European safety standards. Rated IP20, they’re designed so fingers can’t reach the electrical parts inside and get shocked. They also meet UL 94 V-0, so if they catch fire, they’ll self-extinguish within 10 seconds and won’t spread the fire by dripping.

Enclosure Humidistats


Reduce the humidity in your enclosure to prevent condensation that can cause corrosion and short circuits. These humidistats switch your heater on when the enclosure reaches the relative humidity setting. Once the humidity falls by 5%, the heater switches off. To install, clip humidistats to a DIN rail.
Nonadjustable humidistats work for most applications. They keep humidity below 65%, which is when condensation is most likely to form. Since they aren’t adjustable, the humidity setting can’t be tampered with or accidentally changed. For critical components, use adjustable humidistats to set the relative humidity you need in your enclosure. Use a lower humidity setting in damp environments and places with frequent temperature changes. Condensation is more likely in these situations.
CSA Certified, CSA-US Certified, CE Marked, and VDE Certified, these humidistats meet American, Canadian, and European safety standards. They also meet UL 94 V-0, so if they catch fire, they self-extinguish within 10 seconds and won’t spread the fire by dripping.

Remote-Sensing Enclosure Heaters


A sensor attached to the heater might signal that it’s warm enough near the heater, while other parts of the enclosure are still cold. Moving the sensor away from the heater helps you keep electronics warm and dry, anywhere in the enclosure. For even heat, a fan blows upward to circulate warm air.
Choose a heater that clips to DIN rail or one that mounts to the bottom of your enclosure. Add a sensor (sold separately) that reaches the part of your enclosure you need to keep warm.
Heaters with humidistats switch on to reduce condensation when the relative humidity gets too high.
Heaters meet American, Canadian, and European safety standards. They also meet UL 94 V-0, so if they catch fire, they self-extinguish within 10 seconds and won’t spread the fire by dripping.
