by The Leading Enterprise Internet of Things Solution Wireless Pressure Meters General Description Features of Monnit ALTA Sensors The ALTA wireless pressure meter measures pressure Wireless range of 1,200+ feet through 12+ walls * in a gas, liquid or vapor supply line and transmits Frequency-Hopping Spread Spectrum (FHSS) the pressure measurement to iMonnit. This solution Improved interference immunity combines a standard pressure transducer interfaced to Improved power management for longer battery life ** a Monnit ALTA wireless radio. (12+ years on AA batteries) Encrypt-RF Security (Diffie-Hellman Key Exchange + Measure pressure with 50 or 300 PSIG AES-128 CBC for sensor data messages) transducers (others available upon request) All ALTA sensors now have up to 3200 readings: Measure non-caustic liquid or vapor pressures - 10-minute heartbeats = 22 days Pressure transducer is NEMA 4X (IP66), CE - 2-hour heartbeats = 266 days Rated Over-the-air updates (future proof) Free iMonnit basic online wireless sensor monitoring and notification system to configure sensors, view Principle of Operation data and set alerts via SMS text and email By connecting the ALTA wireless pressure meter to Actual range may vary depending on environment. a pressurized gas, liquid or vapor supply line, it can * measure the pressure within the line and send data to Battery life is determined by sensor reporting ** the iMonnit Online Sensor Monitoring and Notification frequency and other variables. Other power options System. The data is stored in the online system and are also available. can be reviewed and exported as a data sheet or graph. User customization allows you to set notifications and Wireless Range Comparison alerts from the system so you can know immediately if Wireless Range Comparison pressure is above or below an optimal range.

Please take care when connecting a power device. * ** At temperatures above 100C, it is possible for the board circuitry to lose programmed memory. Power Options 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 3.03.6 V power supply. 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. PAGE 2
