Modus W Series

General Eastern Liquid

Differential Pressure

Transmitters

The Modus W Series pressure transmitters are

designed to measure low differential pressures

of liquids or gases. A wide selection of standard

pressure ranges and electrical ratings is available.

The transmitters are housed in a compact,

heavy duty, gasketted, cast aluminum

enclosure designed to IP 65 of IEC 529

standards and Type 4. The die cast aluminum

enclosure incorporates a recessed neoprene

gasket to prevent the ingress of moisture or

dust. Wall mounting holes are enclosed in

the cast aluminum box and concealed by the

cover. The wall mounting holes and the cover

attaching screws are outside the gasketted

area.

These transmitters feature no moving parts

to wear out, a proven long term stability of

piezoresistive devices, only 316 stainless steel

in contact with the ﬂuid, and an all-welded

construction.

Modus W Series transmitters are an excellent

choice for many HVAC, process and automation

monitoring requirements. Typical applications

include measurement of differential pressure

across ﬂow elements, heat exchangers, pumps

and ﬁlters, liquid level monitoring and other

demanding differential pressure measurement

and control applications.

Access to the electrical terminals are made

through knockouts on the front of the box. A

choice of two knockouts and three hole sizes

are available to accommodate usage of 0.5

in (12.7 mm) conduit or metric sizes PG11 and

PG13.

Pluggable terminal block connectors are

provided with wire protection and captive

terminal screws.

The Modus W Series includes one model:

Model W30.

Advanced Sensors

This model is available with the following power and

signal conﬁguration:

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.

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.
