Wireless Pressure Sensor

The Monnit WIT Wireless Pressure Sensor is capable of measuring gas, liquid or vapor pressures from 0-160 PSI. This sensor can be used anywhere a pressure gauge can be used. Requires 12 – 32 VDC input. This solution combines a standard pressure transducer interfaced to a Monnit Wit wireless radio. The Pressure Transducer is NEMA 4X, CE rated. User customization allows you to set notifications and alerts from the system so you can know immediately if pressure is above or below an optimal range.

Need Longer Battery Life?
Monnit WIT2 Sensors provide the same features and benefits of our standard sensors but with the added value of AA batteries. The AA battery option is more robust at a wider temperature range and provides extremely long life for quicker heartbeats.

2 replaceable AA 1.5V batteries.
At 1 hour heartbeat setting, included AA batteries will last more than 4 Years. **
Robust sensor housing.

** Battery life is determined by sensor reporting
frequency and other variables.
