DESCRIPTION
The Tek-Sub 4800A PTFE Submersible Level Transmitter has been designed for continuous submersion in aggressive fluids. This submersible device uses a rugged ceramic pressure sensor encased in PTFE housing that provides excellent corrosion resistance in most fluids. It facilitates simple installation, easy cleaning and years of trouble-free service with almost no maintenance. The device guarantees stability and reliability in harsh environments.The Tek-Sub 4800A operates on 12-36 VDC power. Available outputs are 4-20 mA, 0.5-4.5 VDC or RS-485.
