This model is available with the following power and

signal configuration:

Model W30

• Two-wire

• DC Voltage In

• 4 to 20 mA out

The span or zero adjustment is performed with a

20-turn potentiometer for fine resolution. A 50%

adjustment in output is possible.

The Series W transmitters comply with the European

requirements of Council Directive 2004/108/EC.

Operation

The pressure transmitter consists of two high accuracy

piezoresistive sensors with stainless steel isolation

diaphragms. Both sensors measure static pressure, and

the difference between these two measurements is

computed electronically. The use of high accuracy and

stable sensors makes this measurement possible. Since

each sensor measures the full static pressure, there is

no possibility of over-pressurizing the transmitter if one

sensor is disconnected from the line. No complex and/

or expensive balancing valves are needed.
