Product Description
The DMD 341 is a very small compressed air differential pressure sensor suited to installations inside compact systems requiring many sensors for monitoring the switching and delivery of compressed air to plant machinery. The DM341 can also be used to monitor high air flow rates in heating and air conditioning systems.
The DMD341 is used to measure pressures in the range of 0-6 mbar up to 0-1000 mbar differential.
Output signals of 4-20mA, 0-20mA or 0-10Vdc can be chosen for the DMD341 to suit the signal conditioning of most air handling management systems.
The low cost Aluminium construction and incorporation of, for air only sensor components, makes the DMD-341 an economical choice for large quantity applications.
For applications requiring the measurement of air pressure in both directions the DMD341 can be supplied with either 12mA +/-8mA, 10mA +/-10mA or 5Vdc +/-5Vdc signal out.

Product Help
Controlling atmospheric pressure
We require a fan system to speed up or slow down if air pressure is below or above atmospheric pressure in the sensing environment. According to our test results we find that the blower cannot exceed 500Pa.
To measure both negative and positive pressures no higher than 500Pa we would suggest The DMD 341 with a -6 to +6 mbar range.
- SKU ID: s1-dmd341-0004
- Part No: 330-S006-1-2-G-100-Q0096-000
- Differential Pressure Range: -6 to +6 mbar
- Output Signal: 4-20mA (2 wire)
- Accuracy: 2% FS
- Electrical Connection: DIN plug connector
- Process Connection: G1/8 female
- Media Compatibility: Non-aggressive gases and compressed air
Push & pull fans blockage monitoring
My application is in the cotton industry, and we would like to measure the pneumatic pressures from -100 to +100 mbar on our various push and pull fans to monitor for blockages. I am interested in a 12 +/- 8 mA option.
We would suggest the following DMD341 specification with a bi-directional range with 12mA output for a zero pressure reading:
- SKU ID: s1-dmd341-0001
- Part No: 330-S100-S1-8-100-Y00-6-000
- Pressure Range: -100 to +100 mbar diff
- Output Signal: 12+/-8 mA (2 wire)
- Electrical Connection: DIN plug connector
- Pressure Connection: 6.6mm dia tube for 6mm dia flexible tubing
Dust collector constant flow
We wish to control a VFD on a dust collector system with a DP sensor to maintain a constant flow and reduce energy costs. The typical DP readings are 1000-1500Pa. Can the DMD341 sensor do this?
We would suggest the DMD341 with a standard 0 to 20 mbar range which is equavalent to a 0 to 2000 Pa.
- SKU ID: s1-dmd341-0002
- Part No: 330-0200-1-3-100-Y00-6-000
- Differential Pressure Range: 20 mbar
- Output Signal: 4-20mA (2 wire)
- Accuracy: 2% FS
- Electrical Connection: DIN plug connector
- Process Connection: 6.6mm dia tube for 6mm dia flexible tubing
- Media Compatibility: Non-aggressive gases and compressed air
