DESCRIPTION MLH Series pressure sensors combine Application Specific The MLH has six standard output options: Integrated Circuit (ASIC) technology with a media isolated, A. 0.5 Vdc to 4.5 Vdc ratiometric from 5 Vdc excitation metal diaphragm design. This digitally compensated sensor B. 4 mA to 20 mA offers value and performance, making it the ideal pressure C. 1 Vdc to 6 Vdc regulated sensing solution for demanding applications. Fully temperature D. 0.25 Vdc to 10.25 Vdc regulated compensated, calibrated and amplified, the MLH is available in E. 0.5 Vdc to 4.5 Vdc regulated 50 psi to 8,000 psi pressure ranges. 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 POTENTIAL APPLICATIONS All metal wetted parts for use in wide variety of fluid Compressors applications Refrigeration and HVAC/R No internal elastomeric seals mean no o-ring compatibility General industrial issues General hydraulics Amplified outputs eliminate cost of external amplifiers Multiple transportation applications including braking and Input reverse voltage protection guards against mis-wiring alternate fuels Less than 2 ms response time provides accurate, high Medical speed measurement Rated IP65 or better for protection from harsh environments 1 Table 1.
