Amphenol M30-03E-A-2-R General eastern differential pressure transmitter Datasheet

Modus M Series
General Eastern
Differential Pressure
Transmitters
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.
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
mounting holes and the cover attaching screws

Advanced Sensors
are outside the gasketted area. Access to the
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
• DC Voltage In
• 4 to 20 mA out
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.
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 capacitance cell is capable of sensing very low,
negative or differential pressures.

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.
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.
