Description
The 45HE Series SWICHGAGE ® is a monitoring and alarm/shutdown device for industrial requirements. It combines state-of-the-art Hall effect switching and analog indication for Pressure,
Temperature or Level applications depending on the model used.
The 45HE is ideal for use with DC powered solid state controllers because it operates with
Normally Open or Normally Closed Systems from 4.5 to 28 VDC. 120 VAC On-Off control available in Latching Control Relay (BP) models.
Most 45HE models are available in surface mount or panel mount case designs. Dials are dual scale, single scale, and custom dials are also available.
Basic Operation
Based on our proven OPL, SPL and OPLH Series
SWICHGAGE ® models, the 45HE Series includes two magnetic-field-actuated PowerHall* transistors. When the magnetized indicating pointer meets one of the
Hall effect devices, the corresponding alarm or shutdown

Applications
The 45HE Series SWICHGAGE ® models accurately and reliably measure, indicate and control pressure, temperature and level in applications such as gas compressor control panels, pumping applications, industrial process applications.
45HE models are available for specific applications such as monitoring oil well lead lines, storage tank levels, automatic ON/OFF pump control, etc.
Features
PLC and Solid State Compatible
The Normally Open and Normally Closed versions of the 45HE Series are suitable for Murphy
(and others) solid state TATTLETALE ® annunciators and logic controllers, PLC’s and microprocessor-based controllers.
Low Switch Start-Up Override
A standard toggle switch is provided (N.O. and N.C.
surface mounted models) to override the low switch during equipment start-up.
Latching Control Relay (BP Model)
The 45HEBP Series includes a latching control relay for automatic ON/OFF control, either directly or through a motor starter.
Freeze-proof Sensing (FP Model)
A freeze-proof sensing device is available for the
45LHE Series level SWICHGAGE ® . The freezeproof device inserts directly into the tank wall.
The 45LHEFP sensor is stainless steel with a
Buna-N rolling diaphragm.
Optional Features
Remote Transmitter Option (-P4)
This factory-sealed, remote pressure transmitter protects the 45PHE sensing element from line pressures of highly viscous and mildly corrosive fluids.
A 5 foot (1.5 m) stainless steel capillary tube transmits pressure from the diaphragm seal to the unit.
A 1 NPTM plated steel pulsation dampener is included to help prevent damaging pulsation.
Direct Transmitter Option (-P6)
The -P6 option is the direct mounted version of the
-P4 (remote transmitter option). This factorysealed mechanism consists of a 2 NPTM plated steel diaphragm housing (304 stainless steel diaphragm housing is optional), which attaches directly to the 45PHE pressure SWICHGAGE ® .
Explosion-proof Option (-EX)
Most 45HE Series SWICHGAGE ® devices are available with an explosion-proof case for hazardous applications.
Warranty
A two-year limited warranty on materials and workmanship is given with this Murphy product.
Details are available on request and are packed with each unit.
