General Eastern

Differential Pressure

Transmitters

are outside the gasketted area. Access to the

The Modus M Series family of differential pressure

transmitters measure low pressures, and feature

a variety of analog signal outputs with low power

consumption. A wide selection of standard

pressure ranges and electrical ratings is available.

These transmitters feature no moving parts to

wear out, reliable long term stability, and are

virtually position insensitive. The Modus M Series

transmitters are typically used for monitoring

cleanroom pressures, HVAC, velocity pressures,

bubbler level systems, and leak detection; as well

as ﬁlter differential, draft, fume hood, and other

low pressure applications.

terminals is made through knockouts on the front

of the box. A choice of two knockouts and three

hole sizes is available to accommodate usage of

1/2 in (12.70 mm) conduit and metric sizes PG11

and PG13.

Pluggable terminal block connectors are provided

with captive wire protection and captive terminal

screws.

The Modus M Series includes the M30 Series:

•ꢀTwo-wire

•ꢀDCꢀVoltageꢀIn

•ꢀ4ꢀtoꢀ20ꢀmAꢀout

The transmitters are housed in a compact

heavy duty, gasketted, cast aluminum enclosure

designed to Type 4/IP 65. The die cast aluminum

enclosure incorporates a recessed neoprene

gasket to prevent ingress of moisture or dust. Wall

mounting holes are enclosed in the cast aluminum

box and concealed by the cover. The wall

The span or zero adjustment is performed with a

20 turn potentiometer for ﬁne resolution.

The Modus M Series transmitters comply with

the European requirements of EMC Directive

2004/108/EC, LVD 2006/95/EC and PED 97/23/EC.

Advanced Sensors

A very lightweight, responsive diaphragm within the

cell deﬂects a small amount when a small pressure

is applied. This deﬂection results in a change in

capacitance which is then detected and ampliﬁed

electronically.

Operation

The pressure sensing element is a differential

capacitance cell for pressure measurements ranging

from 0.1 in to 5 in (3.04 mm to 127 mm) of water (25

kPa to 1.0 kPa), or piezoresistive (silicon) sensors for

pressure measurements ranging from 5 in (127 mm) of

water to 10 in (1.0 kPa to 2.5 kPa).

The piezoresistive sensor is a solid state device

designed in a Wheatstone bridge conﬁguration. When

pressure is applied to the device, the resistance of the

bridge changes by a small amount. The output of the

bridge is ratiometric to the supply voltage, and a small

change in resistance is detected as a change in output

voltage.

The capacitance cell is capable of sensing very low,

negative or differential pressures.

*If the measured differential pressure is expected to go from positive to negative, a

transmitter with offset (elevated zero) should be ordered.

Three options are available:

“0” No offset. At zero differential pressure, the output signal is:

4 mA (4 to 20 mA range)

Pressure excursion

0% to 100% of range, see standard pressure ranges tables on page 4

“A” 1/4 span offset. At zero differential pressure, the output signal is:

To order: Determine the positive pressure range. From standard pressure

ranges table on page 4, ﬁnd the corresponding pressure code. Add the required

offset (none, A, or B).
