Wireless Pressure Meters

Unique AA battery-powered sensor measures line pressure: gas, liquid, or vapor. These meters remotely monitor machines, pumps, or specialized areas (e.g., labs, negative pressure tents for health care, and cleanrooms). Choose from 50 or 300 PSIG meters.

Wireless Button Press Sensors

Does the restroom need service? Want to confirm system network performance? Press an on-sensor button to trigger an alert and see the on-unit LED illuminate—know help is on its way or that sensor placement is optimal.


 Voltage Detection Sensors

Each sensor in this award-winning family wirelessly monitors for a specific danger: carbon monoxide (CO), hydrogen sulfide (H2S), or carbon dioxide (CO2). If gas exceeds user thresholds, an alert is issued. Use to maintain worksite compliance and safety.

Wireless Resistance Sensors

These sensors read the resistance across a resistive load up to 250K Ohms—great for typical industrial or scientific equipment. An alert is sent if levels deviate from user-set limits; data is collected to support analysis and action. Wireless power over-air  

 Ultrasonic Ranging Sensors

An ultrasonic sensor measures the distance between itself and an object(s) in its path to detect liquid levels, track inventory, or monitor traffic. Both commercial and industrial-grade ultrasonic sensors are offered for manufacturing, logistics, and process industries.
