Robust differential pressure transmitters for industrial applications

TDK Corporation has extended its MiniCell range to incorporate pressure transmitters in robust stainless-steel casing that measure differential pressure in industrial applications. The B58622M32* series includes five models that measure between 0 to 500mbar and 0 to 10bar. Its compensated temperature range extends from -20C to +140C, and the dimensions are 57mm x 34mm x 39mm, including the connections.

MiniCell provides media resistance with high-alloy AISI 316L steel membrane on pressure ports that transmit the pressure to the sensor die through oil-filled, media-separated sensor cells. The medium, which facilitates pressure measurement of aggressive liquids and gases, does not come into direct contact with the sensor die.

The compact pressure transmitters provide two pressure ports of G 1/8″ size and an M12 plug for the electrical connection, with a casing that meets IP67 protection class demands. The product is fitted with a screw connection, and the device can be constructed in any position without impairing measurement accuracy. Its integrated signal conditioning offers a calibrated analog output signal of 0.5V to 4.5V with high immunity against EMI. The transmitters deliver a very high level of precision over the complete pressure range of ±1.5% FS in the temperature range of -20C to +140C.

The transmitters are ideal for demanding industrial applications in automotive test systems, pumps, compressors, hydraulic and pneumatic systems, and systems for energy and water management. Typical applications comprise fill level measurement, leakage detection, flow control and filter monitoring.
