Description
The Keller LEO3 is a micro-processor based pressure transmitter with a digital 2-line display. The transmitter indicates the current pressure as well as the loop powered (2 wire) 4-20mA output value or the last registered minimum or maximum pressure.
The LEO3 is available in five pressure ranges, including: 0-4 bar, 0-30 bar, 0-300 bar, 0-700 bar, and 0-1000 bar
The LEO3 calculates the pressure up to 90 times per second to an accuracy of 0.2% of full scale. The transmitter for the LEO3 is temperature compensated from 0 to 50°C and has a G ¼” process connection. The LEO3 is IP65 rated for protection in a wide range of environments.
All functions of the LEO3, including output configuration, MAX/MIN display and reset, selecting pressure units and zeroing are easily done via two front keys.
