Wireless Temperature and Humidity Transmitters

Use smartphones and tablets to monitor humidity and temperature within your system or facility. Connect these battery-powered transmitters to your smart device via Bluetooth, and receive data to ensure workplace conditions are suitable for processes, inventory, or personnel. Good for preventative maintenance and route-based monitoring, these transmitters let you choose how frequently you receive the data, and they’ll notify your device when humidity and temperature levels go outside of your thresholds. Download the app, set your parameters, and collect data from up to 300 ft. away. Rated IP65, they are protected against dust and washdowns.

Turn your transmitter into a portable monitoring system by attaching a quick coupling (not included). This allows fast, temporary connections for on-the-go measurements in different locations.

Temperature and Humidity Transmitters


	A-Code, 4-Pole Male

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


Fixed Actuation Point	Adjustable Actuation Point

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.

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.

Fixed Actuation Point—Fixed 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.

Adjustable Actuation Point—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.
