This digitally alternative fuels compensated transducer offers value and performance, Medical: Anesthesia delivery machines, blood analyzers, making it a suitable pressure sensing solution for demanding chemistry analyzers, gas chromatography, oxygen applications. Industry standard electrical connectors and concentrators, and ventilators pressure ports are offered for enhanced reliability and user flexibility. PORTFOLIO The MLH Series joins the PX3 Series, PX2 Series, SPT Series The MLH Series has six standard output options: heavy duty pressure transducers and the 13 mm Series and Ratiometric: 0.5 Vdc to 4.5 Vdc from 5 Vdc excitation 19 mm Series heavy duty pressure transducers. Current: 4 mA to 20 mA Regulated: 1 Vdc to 6 Vdc Figure 1. Total Error Band (TEB) Definition Regulated: 0.25 Vdc to 10.25 Vdc Regulated: 0.5 Vdc to 4.5 Vdc Sources of Error Regulated: 1 Vdc to 5 Vdc Offset Full Scale Span VALUE TO CUSTOMERS Pressure Non-Linearity Total Accuracy Total Error Band (TEB) as low as 2 %FSS from -40C Pressure Hysteresis Error BFSL to 125C: Provides indication of the transducers true Pressure Non-Repeatability Band measurement performance over a specified temperature Thermal Effect on Offset range small error promotes system uptime and efficiency. (See Thermal Effect on Span Thermal Hysteresis Figure 1.) All metal wetted parts allow for potential use in a wide variety of fluid applications. No internal elastomeric seals eliminate 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.

Pressure Reference Types Pressure Reference Description Output is proportional to the difference between applied pressure and a built-in fixed reference to 1 Sealed gage 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 2 Vented gage (relative) between applied pressure and atmospheric (ambient) pressure, where the minimum operating pressure is set to atmospheric pressure. 2 Sensing and Internet of Things
