Wireless Pressure Meters


Product Description

ALTA wireless pressure Meters measure pressure from a 5 volt pressure transducer and transmits the pressure measurement to iMonnit. By connecting the Monnit 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 iMonnit 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.


ALTA – Leading Enterprise Grade “Internet of Things” Solutions

ALTA sensors offer 3 to 4 times the range of standard sensor platforms, extending non-line-of-sight reach to an exceptional 1,000+ feet through walls (12-14 walls typical). Using Frequency-hopping Spread Spectrum (FHSS) also allows ALTA sensors to have better interference immunity from other wireless devices.

Superior power management provides ALTA sensors with almost twice the battery life of Monnit’s standard wireless sensors.

  – Coin cell sensors typically last 3+ years.

  – AA and Industrial sensors typically last up to 10+ years.


ALTA products employ Monnit’s new Encrypt-RF™ Security (256-bit Diffie Hellman key exchange and AES-128 CBC encryption for all sensor data messages), so security is maintained at all communication points from sensor to gateway, gateway to software, then back again.


Integrated on-board data storage allows ALTA sensors to store data messages if communication to a wireless gateway is disrupted (power outage, Internet outage, or out of range). Messages that can’t be delivered will be time-stamped and stored in memory (up to the last 3100 messages) until communication with the gateway is restored, at which point the messages will all be transmitted.


Over-the-air updates allow ALTA products to be updated remotely if new fixes or features become available.


Monnit ALTA Industrial Sensors come in an IP65, NEMA 4X, CE rated, sealed, and weatherproof enclosure. They are powered by a single, replaceable, Industrial grade 3.6 V battery (included).


An optional solar powered version is also available. The solar powered version includes a Lithium Iron Phosphate rechargeable battery in conjunction with a solar power cell to keep the battery charged and at optimal capacity. If there is no light present at the solar cell, the battery alone could continue to power the sensor for up to 8-10 years.


  – Works with Gas, Liquid or Vapor.

  – No External Power Required.

  – Measures pressure from 0-300 PSIG.


  * Actual range may vary depending on environment.
** Battery life is determined by sensor reporting frequency and other variables.
