Keller LEO3 Digital Manometer (31bar)
Capable of both relative and absolute pressure measurement, the Keller LEO3 Digital Manometer works as both a pressure signal transmitter and a digital pressure gauge. It has an absolute pressure measurement range of 0 to 30bar and a relative pressure range of -1 to 31bar. Readings are accurate to ±0.1% FS and have a resolution of 10mbar. They are taken through the manometer’s G1/4” male connection.
The Keller LEO3 can show measurements on screen in a number of different units. It has a min/max feature where the highest or lowest reading is displayed alongside the current pressure reading. A zero function is available for carrying out relative measurements
In addition to a digital pressure readout, the Keller LEO3 transmits an analogue signal in the form of a 4...20mA current loop. This can be connected to an external system by the manometer’s 723 Binder connection and an optional K114B adaptor. The current loop value is displayed on screen next to the readout and it can also be manually set to 4mA or 20mA for relative measurement.
When the Keller LEO3 is connected to a computer system, the user can use Keller ControlCenterSeries30 software to manage readings from the pressure gauge. The gauge is powered by the current loop and has an IP65 ingress protection rating, ideal for use in challenging conditions.
