Itokii wireless pressure meters measure pressure from a 5 volt pressure transducer and transmits the pressure measurement to Itokii. By connecting the Itokii wireless pressure sensor to a pressurized gas, liquid or vapor supply line, it can measure the pressure within the line and send data to the iTokii Online Sensor Monitoring and Notification System. The data is stored in the online system and can be reviewed and exported as a data sheet or graph. 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.
The standard version of this sensor is powered by two replaceable 1.5 V AA sized batteries (included with purchase). This sensor is also available with a line power option. The line powered version of this sensor has a barrel power connector allowing it to be powered by a standard 3.0 - 3.6 V power supply (Included with Line Power option upgrade). The line powered version also uses two standard 1.5 V AA batteries as backup for uninterrupted operation in the event of line power outage.
Power options must be selected at time of purchase, as the internal hardware of the sensor must be changed to support the selected power requirements.
- Works with Gas, Liquid or Vapor.
- No External Power Required.
- Measures pressure from 0-50 PSIG.
* Actual range may vary depending on environment.
** Battery life is determined by sensor reporting frequency and other variables.
