Keller Submersible Transmitters
Integral cable vent tube for a fast response and accurate readings
Lifetime lightning/surge protection guarantee
Choose from models for wastewater, general-purpose and potable water/down well applications
Keller submersible level transmitters are known for their superior reliability and reasonable cost. They feature rugged construction, a small size and integral signal conditioning—simplifying installation anywhere quality liquid level sensors are needed.
Select models provide dual outputs: the RS-485 connection lets you retrieve both level and temperature data; the analog 4-20 mA is rescalable from 10 to 110% of the basic range using Keller’s Control Center 30 (CCS30) software (free download) and a converter cable (stock # 71767).
Custom Options Available
Custom models are available for all transmitters, and typically ship is less than one week. Options include pressure ranges, cable lengths and wetted materials. Contact USABlueBook Technical Support for more information.
