Endress+Hauser launches new pressure sensor line

Extensive product line aims at sophisticated performance with a budget price.


Endress+Hauser has announced a new line of U.S.-built pressure sensors and transmitters that take advantage of lean manufacturing techniques to provide high performance competitive prices. The company says that the new product family, dubbed the M Class, takes advantage of domestic manufacturing to provide fast delivery, sophisticated capabilities, special designs, and attractive pricing for cost-conscious users. The new line of M-Class transmitters makes it easier for legacy plants to upgrade to digital communications systems such as HART and WirelessHART. The company understands that it can be difficult for a plant to upgrade all its transmitters at one time, but the M-Class allows users to install instruments on an as-needed basis.

M-Class pressure devicesM-Class transmitters use either capacitive or piezoresistive elements depending on model, and have a 4-20 mA two-wire analog output with superimposed HART 6.0 digital communications. Remote operation is available via a HART Field Communicator handheld terminal or the wireless Field Xpert PDA with an integrated 3.5-in. touchscreen. The transmitters can also be configured with Endress+Hauser’s FieldCare asset management tool, based on FDT technology.

An optional four-line liquid crystal display (LCD) can be used for local display and operation on the transmitters and can display measured values and dialog texts as well as fault and notice messages in plain text, thereby supporting the user at every stage of operation. The liquid crystal display of the device can be turned in 90° stages.

M Class devices are suitable for most traditional pressure sensor applications, including absolute and gage pressure, differential pressure, differential pressure flow measurements, liquid level measurements, and others.
