## DESCRIPTION 

The MLH Series Heavy Duty Pressure Transducers combine Application Specific Integrated Circuit (ASIC) technology with a media-isolated, metal diaphragm design. This digitally compensated transducer offers value and performance, making it a suitable pressure sensing solution for demanding applications. Industry standard electrical connectors and pressure ports are offered for enhanced reliability and user flexibility. 

The MLH Series has six standard output options: 

- Ratiometric: 0.5 Vdc to 4.5 Vdc from 5 Vdc excitation 

- Current: 4 mA to 20 mA 

- Regulated: 1 Vdc to 6 Vdc 

- Regulated: 0.25 Vdc to 10.25 Vdc 

- Regulated: 0.5 Vdc to 4.5 Vdc 

- Regulated: 1 Vdc to 5 Vdc 

## VALUE TO CUSTOMERS 

- Total Error Band (TEB) as low as 2 %FSS from -40°C to 125°C: Provides indication of the transducer’s true measurement performance over a specified temperature range; small error promotes system uptime and efficiency. (See Figure 1.) 

## POTENTIAL APPLICATIONS 

- Industrial: Compressors, cylinder tank pressure, HVAC, hydraulics, oil and gas, refrigeration, water distribution 

- Transportation: Multiple applications including braking and alternative fuels 

- Medical: Anesthesia delivery machines, blood analyzers, chemistry analyzers, gas chromatography, oxygen concentrators, and ventilators 

## PORTFOLIO 

The MLH Series joins the PX3 Series, PX2 Series, SPT Series heavy duty pressure transducers and the 13 mm Series and 19 mm Series heavy duty pressure transducers.

## 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.
