This model is ideally designed to monitor the differential air pressure in critical containment applications like pharmaceutical manufacturing, isolation rooms, cleanrooms, research labs, hospitals, and vivarium, as well as various other applications.
The user-friendly colored touch-screen displays various menus to guide the user through setup and provides visual indication of room status.
The large LCD screen makes the pressure reading and alarm status clear. If pressure is beyond the set alarm range, it activates the audible and visual alarms, alerting personnel to the alarm condition. It features a mute button to avoid nuisance alarms.
Product Overview
In certain healthcare environments, it’s mandatory to maintain air differential. This is essential for the safety of staff as well as to be in positive pressure to avoid room contamination, while isolation rooms need to be in negative pressure to prevent spreading contamination through the building.

Product Features
Differential Pressure Transmitter
The differential pressure transmitter (without LCD) is an economical solution with selectable measuring pressure range and automatic zero-point adjustment. The enclosure of this transmitter is USE-L, PC, pure white, with removable cable entry, and includes screw mounted onto flat surface prepared for mounting on DIN rail.
4.3" Touch Screen
The user-friendly 4.3” touch-screen with graphical view, intuitive control menus, easy to set-up and password protection for setting menus. It also has audible and visual alarm via flashing colored diffused LED.
Automatic Zero Point Correction
The auto-zero correction electronically adjusts the transmitter zero every 10 minutes. The function eliminates all output signal drift due to thermal, electronic, or mechanical effects. The auto-zero correction takes approx. 4 seconds after which the device returns to its normal measuring mode. During the 4-second correction period, the output and display values will freeze to the latest measured value.

Additional Sensors
Air flow Sensor- the AFT-D airflow transmitters are engineered for building automation in the HVAC/R industry. The most technologically advanced transmitters on the market, measuring volume flow, velocity, These sensors can be connected directly to the room pressure monitor to provide the pressure measurements points in a centrifugal fan, providing accurate flow measurement of the fan.(selection of settings according to the selected fan or in-duct measurement probe).
Measurement Probe- the R160 probe is a differential air pressure device designed to measure air volume flow in a duct. It includes multiple sensing points to measure total and static pressures. It incorporates a unique design to amplify the differential pressure by 2.5 times for accurate measurement of lower air velocities down to 1.0 m/s (200fpm). It is easy to install and cost-effective.

Differential Pressure Switch (PS)
Differential Pressure Switch (PS) - this is ideal for air filter monitoring like HEPA Filters, static pressure proving, airflow proving or auxiliary fan actuation. The unit features a rugged plastic enclosure that protects the electrical terminations and pressure adjustment screw, which is easily accessed through a port in the front cover using a square screwdriver. It is very compact and can be mounted directly on a flat surface with the rugged mounting feet.
