Keller Series M5 HB Pressure Transmitter

The Keller Series M5 HB Pressure Transmitter was designed to take advantage of the high dynamic range of the M5 sensor head. The signal path remains entirely analog, although it is readjusted in real time by means of a high-precision digital compensation circuit. This ensures the full dynamic range of the sensor and the accuracy of the measurement signal are maintained across the entire 0 to 50 kHz bandwidth. With a temperature range of -40 to 257°F (-40 to 125°C), the remote signal converter satisfies the exceptional demands associated with hostile environments.

The Series M5 sensor incorporates a stable silicon sensor which is backside-soldered directly to a supporting element designed for excellent fluid dynamics. This construction eliminates the disadvantages of sealants, adhesives, separating membranes or capillary tubes in high temperature environments. The practically-flush connection to the measurement media is critical to the excellent dynamic range of 0 to 50 kHz. The micromechanical design delivers absolute measuring ranges of 3, 10 and 30 bar, over pressure protection of up to 5 times measuring range and effective isolation of mounting forces.
