The Keller Valueline high accuracy pressure transmitter combines piezoresistive silicon sensor technology with Keller's state-of-the-art signal conditioning circuitry to make a very reliable transmitter with excellent Total Error Band (TEB) accuracy over a wide compensated temperature range.

The ability of the Valueline to provide this level of sustained performance over a wide range of operating conditions makes it ideally suited to pressure monitoring applications such as tank level measurement, pump control, and VFD control.

Additionally, models equipped with 4-20mA analog output include guaranteed lightning protection at no additional cost. This feature protects the pressure transmitter from fast-rising transients and carries a lifetime guarantee against damage from electrical surge making it perfect for installation in areas prone to chronic damage due to transients caused by lightning.
