Pressure switches, Transducers and
Pressure Indicators
Series PM: adjustable-diaphragm pressure switches,
with visual scale, with exchange contacts (SPST, SPDT)
Series TRP: electro-pneumatic transducers
Series 2950: pressure indicators, ports M5
Series PM diaphragm pressure switches
are available with NC (normally closed)
contacts and with NO (normally open)
contacts.
Series PM681 pressure switches
with setting visual scale comply with
EN60730 standards and are suitable for
signaliing pressure through a normally
open Reed contact.
A regulating screw, which can be
adjusted using a small screwdriver,
allows the switch to be set to the
required pressure.
The calibrated diaphragm enables an
electrical signal to be generated or
inhibited depending on the pressure set.
