Differential pressure controllers

The ATEX certified AT2DH3 series Digihelic® differential pressure controller is a 3-in-1 instrument that consists of a digital differential pressure gauge, relay contacts for alarms, or on-off control and a transmitter output. The AT2DH3 can also be used to measure air velocities and flow in combination with a pitot tube. The AT2DH3 has an analogue 4-20 mA output and two SPDT relay contacts with…

The Dwyer DH3 series Digihelic differential pressure gauge is a 3-in-1 instrument with a digital display, relay contacts and a transmitter output, all packed in the popular Photohelic housing. By combining these 3 functions, you can reduce different instruments to one product, saving you inventory, installation time and money. The DH3 controller is the ideal instrument for pressure (difference) m…

In addition to differential pressure, the MF-PFC transmitter also measures air velocities in combination with the MFS self-averaging flow sensors. The transmitter has 2 analog outputs that can be used for differential pressure, flow or PI control output. For example, the control output can be used to directly control a VAV valve. High accuracy and stability make the MF-PFC ideal for use in labora…

The MF-PFA series can measure the airflow in combination with the self-averaging MFS flow sensors in addition to differential pressure. Besides analog outputs, this series also features a built-in PI controller, which can directly controll a fan and 2 swithes for local alarms. Due to the high accuracy and stability, the MF-PFA is ideal for use in laboratories, hospitals and clean rooms. Each inst…

The MF-PFT series can measure the airflow in combination with the self-averaging MFS flow sensors in addition to differential pressure. Besides analog outputs, this series also features a built-in PI controller, which can directly controll a fan. Due to the high accuracy and stability, the MF-PFT is ideal for use in laboratories, hospitals and clean rooms. Each instrument is fully programmable.
