MLH Series, 6 bar to 550 bar | 50 psi to 8000 psi

GENERAL INFORMATION Transducers with a gage (relative) reference are vented to the atmosphere through a case vent hole that is protected with a vapor inhibiting material.

Ratiometric voltage devices require a regulated 5.0 Vdc supply. All other versions can use an unregulated supply within the ranges noted under the excitation specifications. The power supply should be off while wiring.

PRESSURE OVERLOADS
CAUTION
PRODUCT DAMAGE
 Do not exceed the pressure overload rating. Failure to comply with these instructions may result in reduced life, or electrical failure.
The MLH Series pressure transducers will withstand high overloads; however, if the overload rating is exceeded, the life of the MLH Series may be reduced and electrical failure may occur. Both static and dynamic overloads must be considered, particularly in hydraulic system applications. Hydraulic pressure fluctuations can have very high and very fast peak pressures, as in a water hammer effect.
An oscilloscope is recommended for determining if high pressure transients exist in a system. If system pressure pulses are expected, choose a transducer with a pressure rating high enough to allow continuous operation at the highest expected pressure spikes.
A pressure `snubber' may be used to reduce the peak pressure applied to the transducer.
MEDIA COMPATIBILTY
CAUTION
PRODUCT DAMAGE
 Use non-abrasive, chemically compatible media to prevent damage to the diaphragm or pressure port materials.
Failure to comply with these instructions may result in product failure.

ELECTROMAGNETIC ENERGY/NOISE
CAUTION
PRODUCT DAMAGE/ERRATIC OPERATION
 Do not use in areas where electromagnetic energy may affect transducer operation.
Failure to comply with these instructions may result in improper operation and/or product failure.
The MLH Series has been rated for high immunity to electrical noise; however, care should be taken when used around high voltage sources that emit high levels of radiated electromagnetic energy like variable frequency motor drives, solenoids, radio transmitters and engine ignition systems. The use of shielded cable and grounding of pressure port is also recommended.
BENCH TEST For incoming inspection or transducer failure evaluation: 1. Connect the transducer to a dc voltage supply (off). 2. Set the supply voltage to within the range specified for the
model. 3. Based on the transducer's specified output, connect the
output lead(s) to a digital dc or mA meter. 4. With no pressure on the transducer, turn on the power supply
and read the output signal on the voltmeter. The reading should correspond to the specification indicated for null offset. If not, check the connections, wire color code and the setting of the power supply.
WIRING INSTRUCTIONS The wiring code for electrical connection is shown in Figure 3.

The MLH Series diaphragm and pressure port is an assembly of Haynes 214 alloy and 304L stainless steel.
INSTALLATION
CAUTION
PRODUCT DAMAGE
 Use a hex wrench for installation. Never apply torque to the connector housing or the body of the transducer.
 Do not subject the transducer to high temperatures from soldering, brazing, or welding of the system plumbing or operating environments above the specified maximum temperature.
Failure to comply with these instructions may result in product damage.

When using a connector, the use of the correct size wire is important to ensure environmental sealing. Fill all holes in the connector seal even if only two leads are used. Honeywell recommends using a crimping tool for crimping wires to the connector pins. Contact the individual connector manufacturer for mating connector wiring.

Description

Sealed gage1

Output is proportional to the difference between applied pressure and a built-in fixed reference to 1 atmA, where the minimum operating pressure is set to 14.7 psiA (1 atmA).

Transducer measures pressure relative to ambient pressure. Output is proportional to the difference Vented gage (relative) 2 between applied pressure and atmospheric (ambient) pressure, where the minimum operating
pressure is set to atmospheric pressure.

CAUTION
PRODUCT DAMAGE DUE TO MECHANICAL ISSUES
 Ensure torque specifications are determined for the specific application. Values provided are for reference only. (Mating materials and thread sealants can result in significantly different torque values from one application to the next.)
 When using mating parts made of stainless steel, use a thread sealant with anti-seize properties to prevent thread galling. Ensure the sealant is rated for the application.
 Use appropriate tools (such as an open ended wrench or deep well socket) to install transducers.  Always hand-start transducers into the hole to prevent cross threading and damage.  Ensure that torque is not applied to the electrical connector.  Ensure that the proper mating electrical connector with a seal is used to connect the transducer. Improper or damaged
seals can compromise ingress protection, leading to short circuits. Failure to comply with these instructions may result in product damage.

CAUTION
PRODUCT DAMAGE DUE TO PARTICULATES
 Ensure that a filter is used upstream of the transducer to keep media flow free of larger particulates and increased humidity. All MLH Series transducers are dead-ended devices; particulate accumulation and condensing moisture may affect transducer output.
 It is recommend that the transducer be positioned with the port facing downwards; any particulates in the system are less likely to enter and settle within the pressure transducer if it is in this position.
 Ensure that the media does not create a residue when dried. Build-up inside the transducer may affect transducer output; rinsing of a dead-ended transducer is potentially difficult and has limited effectiveness in removing residue.
Failure to comply with these instructions may result in product damage.
