## **Datasheet** 

## **FEATURES** 

- All metal wetted parts allow for potential use in wide variety of fluid applications 

- No internal elastomeric seals mean no O-ring compatibility issues 

- Amplified outputs reduce the need to purchase external amplifiers 

- Input reverse voltage protection guards against mis-wiring 

- Less than 2 ms response time provides more accurate, high speed measurement 

- Rated IP65 or better for protection from most harsh environments 

## **DESCRIPTION** 

## **POTENTIAL APPLICATIONS** 

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. Fully temperature compensated, calibrated and amplified, the MLH Series is available in pressure ranges of 6 bar to 550 bar | 50 psi to 8,000 psi. The MLH Series provides ±0.25% full scale accuracy Best Fit Straight Line (BFSL) and a TEB (Total Error Band) as low as 2% over a temperature range of -40 °C to 125 °C [-40 °F to 257 °F]. Industry standard electrical connectors and pressure ports are offered for enhanced reliability and user flexibility. 

- 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, 13 mm Series and 19 mm Series heavy duty pressure transducers. 

The MLH Series has six standard output options: A. 0.5 Vdc to 4.5 Vdc ratiometric from 5 Vdc excitation B. 4 mA to 20 mA 

C. 1 Vdc to 6 Vdc regulated D. 0.25 Vdc to 10.25 Vdc regulated E. 0.5 Vdc to 4.5 Vdc regulated 

G. 1 Vdc to 5 Vdc regulated
