Transmitter Measures Pressure Differential

Endress+Hauser has launched the Deltabar FMD72 Electronic Differential Pressure (DP) measurement system. The FMD72 uses two pressure sensor modules connected electronically to a single transmitter, which is designed to eliminate the need for impulse lines or capillaries, as well as issues related to icing, clogging, leaky taps, dry/wet leg inconsistencies and problems with temperature changes.
 
The sensor module measures the hydrostatic (high pressure), the second sensor measures the head pressure (low pressure) and the transmitter calculates the differential pressure. These measured values can be used to calculate the level, volume or mass of liquids in pressurized tanks.
The system meets ATEX, IEC Ex, CSA and FM specifications for use in hazardous areas including Zones 0, 1 and 2; and Division 1 and 2.
 
The transmitter outputs differential pressure, head pressure and temperature via 4-20mA with HART. The sensors have 0.075% accuracy over a measuring range of -15 to 150 psi and work in process temperatures from 40 degrees below zero to 257 degrees Fahrenheit. It also has built-in diagnostics for continuous health indication via HART.
