Pressure
General Description
The ALTA® Wireless PSIG Pressure Meter measures gauge pressure in a gas, liquid, or vapor supply line.
Key Features
Transducers available: 50, 300, 750, 3000 PSIG
Resolution: 0.1 PSI
Accuracy:
- Uncalibrated: ± 2% of reading + 1.05% FS
- Calibrated: ± 0.5% of reading + 0.5% FS
Configurable thresholds for critical condition monitoring
Principles of Operation
The ALTA Wireless Pressure Meter uses an industrial-grade pressure transducer to measure pressure on a user-configurable time interval or Heartbeat. On every Heartbeat, the pressure transducer is energized and a proportional analog voltage is converted to a digital pressure measurement. This measurement is then sent to the gateway, making the data available in iMonnit or another approved data service.
The ALTA Pressure Meter can be calibrated for improved accuracy. Also, remember to remove the pressure from the sensor when performing maintenance on this device.
