DWYER INSTRUMENTS DH3-002 Digihelic Differential Pressure Controller, 4 Digit LCD

Dwyer DH3-002 Digihelic differential pressure controller is suitable for air & gas flow control in damper, fan control and duct flow operations.

Features:

• Dwyer DH3-002 Digihelic differential pressure controller includes control relay switches, a digital display gauge and transmitter for minimising system complexity.
• It delivers full-scale accuracy of 1.5% on extremely low ranges for precise output and digital dampening for smoothing erratic processes.
• This unit has a field calibration feature for easy set-up & on-site calibration and die-cast aluminium housing for durability.
• It comes with 2 SPDT (single-pole double-throw) relays that can be easily connected to the electrical supply.
• The model allows front ring mounting and has an input pressure range from 0 to 0.25 inches W.C. (water column).

Standards and Approvals:

• CE

Frequently Asked Questions:

Q. What are the important points to consider while locating Dwyer Digihelic pressure controller?

A.

• Select an appropriate location that is free from vibration and is within operating conditions.
• Only total loop resistance limits the distance between the transmitter and the receiver.
• Practically any length of tubing can be used, whereas extended lengths will somewhat slow the reaction time.
• Two sets of 1/8 female NPT pressure ports are provided for ease of installation. Make sure to add pipe plugs to block any unused ports.

Q. What is the difference between a static pressure sensor and a differential pressure sensor?

A. A differential pressure sensor, often known as a DP sensor, is a unique kind of pressure sensor that gauges the difference in pressure between two ports on a device. It is distinct from a static or absolute pressure sensor that uses a single port to measure pressure.

Q. What should be the position of the pressure controller for installation?

A. It is calibrated to be used in a vertical mounting position.
