Bus Terminals record differential and absolute pressures.

Press Release Summary:



While able to execute functions such as temperature compensation and avoidance of long-term drift, KM37xx series can also measure pressure using standard Beckhoff Bus Terminal with width of 24 mm. Terminals change measured pressure into electrical signal, and this 16-bit value is available to higher level controller and can be transmitted by over 12 fieldbuses. Series can be used in any situation that requires measurement and monitoring of pressure in nonaggressive gases.

Beckhoff Releases Bus Terminals for Simple and Compact Pressure Measurement



Versatile terminals record differential and absolute pressures

MINNEAPOLIS, March 17, 2009 - Beckhoff Automation has expanded its Bus Terminal system with the new KM37xx pressure measuring terminals. These terminals are designed to record differential and absolute pressures and are a flexible, cost-effective alternative to stand-alone pressure measuring instruments.

In a similar way to electrical signal acquisition, pressure measurement is carried out using a "standard" Beckhoff Bus Terminal with a width of only 24 mm. The compact housing and simple connection system support space-saving and speedy installations.

The pressure measuring terminals change the measured pressure into an electrical signal. This 16-bit value is available to the higher level controller and can be transmitted by over a dozen fieldbuses. The pressure measuring terminals have quick release mechanisms for connecting the measuring hoses. Standard commercial plastic hoses can be used for this purpose. In addition to measuring, the Bus Terminals also execute other functions such as temperature compensation and avoidance of long-term drift.

Three different pressure measuring terminals are available from Beckhoff Automation:

- KM3701: The 1-channel differential pressure measuring terminal measures pressure differences up to an ambient pressure of 7,000 hPa (7 bar) between points.

- KM3702: The 2-channel absolute pressure measuring terminal records pressure values between 0 and 7,000 hPa (7 bar) at each hose connector.

- KM3712: The 2-channel absolute pressure measuring terminal records negative pressure values between -1,000 hPa (-1 bar) and 0 hPa at each hose connector.

Beckhoff pressure measuring terminals can be used in any situation that requires the measurement and monitoring of differential and dynamic pressures in nonaggressive gases. Applications examples include pressure tanks, pressurized cabins, pneumatic and suction systems. The KM37xx measure operating pressures, monitor filters and sieves, check the seal tightness of tanks and assist in position testing of construction elements or monitoring the level of liquids. If flow rates are calculated from the measured pressures, then the KM37xx can also be used for flow measurement. The terminals can therefore be applied in areas such as process engineering, systems engineering, building services as well as heating, ventilating and air conditioning.
