DWYER INSTRUMENTS DM-2012 Differential Pressure Indicating Transmitter, 0.25 Inch WC

Dwyer DM-2012 pressure transmitter senses the difference in pressure between two points and produces 4 - 20mA output signals. It is ideal for fan pressure readings, filter monitoring, measuring static pressure in ducts and displaying bi-directional ranges while sensing pressure fluctuations in buildings.

Working Mechanism:

• It measures the difference in pressure between two points in a fluid or gas system.
• It utilises a diaphragm and strain gauge to detect pressure changes.
• When pressure is applied to one side of the diaphragm, it causes deflection.
• This deflection alters the resistance of the strain gauge, resulting in an electrical output signal.

Features:

• This Dwyer differential pressure transmitter has a hose barb connection, enabling the secure attachment of flexible tubing or hoses.
• It provides a quick response to pressure changes for signalling and alerting in critical situations.
• This features plastic moulded housing for durability and design flexibility.
• It features tamper-proof, digital push buttons for simplifying the calibration through easy access to zero & span settings and preventing accidental changes to settings.
• This CE-approved differential pressure transmitter is equipped with a digital LCD screen to indicate the status of the process and pressure in 4 to 6 engineering units.
• It features barbed fitting for connections between two points.

Frequently Asked Questions:

Q. What does Class SC in fuse mean?

A. Class SC fuses exhibit size-rejecting characteristics concerning their total length, effectively preventing over fusing situations.
