DESCRIPTION MLH Series pressure sensors combine Application Specific Integrated Circuit (ASIC) technology with a media isolated, metal diaphragm design. This digitally compensated sensor offers value and performance, making it the ideal pressure sensing solution for demanding applications. Fully temperature compensated, calibrated and amplified, the MLH is available in 50 psi to 8,000 psi pressure ranges. The MLH 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 MLH sensors deliver ±0.25% full scale accuracy Best Fit Straight Line (BFSL) and as low as 2% total error over a temperature range of -40 °C to 125 °C [-40 °F to 257 °F]. Industry standard connectors and process ports are offered for enhanced reliability and user flexibility. FEATURES All metal wetted parts for use in wide variety of fluid applications No internal elastomeric seals mean no o-ring compatibility issues Amplified outputs eliminate cost of external amplifiers Input reverse voltage protection guards against mis-wiring Less than 2 ms response time provides accurate, high speed measurement Rated IP65 or better for protection from harsh environments POTENTIAL APPLICATIONS Compressors Refrigeration and HVAC/R General industrial General hydraulics Multiple transportation applications including braking and alternate fuels Medical Table 1.
