Product Description

The DS 210 low pressure switch, indicator and sensor utilises an exposed silicon diaphragm for extra sensitivity at low pressures whilst maintaining a high accuracy for the analogue output of 0.35% full scale for ranges above 100 mbar and 0.5% full scale for ranges below 100 mbar.

The digital LED display can be configured by the user to display in any pressure units and the 1 or 2 switch contacts can be set to trigger at any pressure within the range. The DS230 combined low pressure switch, readout and sensor is externally powered via a cable or connector exiting from the top of the instrument which is also used for the analogue output if specified.

Product Applications

Product Help

Number of switches with ATEX version

is it able to configure up to 2 contacts for 2 wire ATEX approved model?

Only 1 contact is possible with the ATEX IS 2 wire 4-20ma output version.

Liquid & gas compatibility

Can the the DS210 be used on liquids or gases, or both?

The DS210 can be used on gases, pressurized air and thin non aggressive liquid media. If you want to use a liquid it is best that you ask before ordering to determine whether it is compatible.

Negative & positive pressure ranges

I see that there are pressure ranges which are positive (100, 250…1000 mbar) and one which is negative (-1000 mbar), but is it possible to combine a negative & positive range in one device?

Yes  it is also possible to offer custom compound ranges such as -1000 to +1000 mbar g or -250 to +500 mbar for example.

Output signal response time

What is the response time of the output signal?

  • 2-wire: ≤ 10 msec
  • 3-wire: ≤ 3 msec

Hysteresis and compare modes

How does the switch work on the DS210 low pressure switch? e.g. could it be configured to switch at 16mbar and 30mbar gauge?

Each contact switch (you can order with up to 4 separate switches) can be used in compare or hysteresis mode.

Compare mode – Switch on at 16 mbar and switch off at 30 mbar, then switch on at 30 mbar and switch off at 16 mbar

Hysteresis mode – Switch on at 30 mbar and turn off at 16 mbar.

Both modes can be inverted if required.

Nitrogen gas up to 2psi

I am looking for a pressure transducer with a visual digital display to measure Nitrogen gas with a maximum temperature of 120°C over 0-2psi, with a 0-10Vdc output signal and installed on a 1/2 NPT process fitting. Also if at any point when measuring the pressure it went negative for a short period of time, say -0.5 psi max, would the sensor be damaged?

The DS210 would meet all your requirements, and it is possible to apply a negative pressure of -0.5 psi without causing any damage.

  • SKU ID: s1-ds210-0002
  • Pressure Range: 2
  • Units: psi
  • Range Type: Positive Gauge (atm to +P)
  • Output Signal: 0-10V (3 wire)
  • Accuracy: 0.35%FS > 0.1 bar, 0.5%FS
  • Switch Output: None
  • Electrical Connection: DIN plug (0-10V 3 wire only)
  • Process Connection: 1/2 NPT male
  • Process Connector Material: Stainless steel 316L
  • Diaphragm Material: stainless steel 1.4404 (316L), silicon, Epoxy or RTV, glass
  • Media Exposed Seals: FKM
