How to Install Monnit ALTA Wireless Differential Air Pressure Sensor

Installing the ALTA wireless differential air pressure sensor is straightforward and designed to minimize disruption to ongoing operations. Follow these steps to achieve a reliable setup that delivers accurate measurements and robust wireless performance:

• Plan your installation location: Choose a stable, vibration-free area with clean air access to both input ports. Ensure the sensor is mounted where ambient conditions do not exceed its operating range and where the wireless signal can reach the gateway without obstructions.
• Prepare the pressure connections: Identify the two ports on the sensor and prepare the corresponding lines or ducts for connection. Use appropriate fittings to ensure a leak-free seal and avoid introducing contaminants into the sensing ports. Remember that the right inlet is the negative or low side when viewed from the top.
• Connect the pressure lines: Attach the two pressure lines to the corresponding input ports. Use seals or adapters as needed to match your piping or ductwork. Take care to route lines in a manner that minimizes stress on fittings and reduces the risk of vibration or blockage.
• Provide line power: Connect the sensor to the designated power supply that complies with the device’s line-power requirement. Verify voltage and termination according to your facility’s electrical standards. Confirm power stability to prevent intermittent data loss.
• Pair with the gateway and enroll in iMonnit: Power up the sensor and initiate device pairing with your iMonnit gateway. Follow the on-screen prompts or your facility’s standard onboarding process to register the sensor ID, assign it to the correct site or zone, and configure basic data refresh rates.
• Tune defaults and set alerts: After enrollment, review measurement units (e.g., Pa, inH2O, or psi) and set alert thresholds for pressure differentials that warrant attention. Create notification rules to trigger emails or SMS when readings exceed safe or expected ranges.
• Calibrate if needed and test: If your application requires a dry-run calibration, perform any recommended calibration procedure according to your process specifications. Verify readings by comparing with a reference point or a calibrated manometer to confirm accuracy before fully relying on automated alerts.
• Document and secure: Record the installation location, sensor serial number, and gateway association for future maintenance. Ensure all wiring and connections are secured in accordance with safety and electrical standards to prevent accidental disconnection.

Frequently asked questions

• What is differential air pressure? Differential air pressure is the difference in pressure between two separate points. The ALTA sensor measures this difference across its two input ports, enabling monitoring of pressure changes in ducts, rooms, and process lines.
