Submersible level transmitters

Model 590 Detachable Level Transmitter

Model 590 Detachable Level Transmitter

The Model 590 Detachable Level Transmitter allows for a quick sensor swap without the removal of the installed cable. No special tools are required. Simply pull up the sensor, twist the sensor coupling sleeve till it is no longer engaged and then simply separate the two halves.

590 is constructed of stainless steel housing and sensor module, with a polyurethane cable as standard.  Different cable materials and o rings are available.

Use it to measure Liquid Level and Depth for Water and Waste Water applications, at Lift Stations, Reservoirs and Dams, Rivers, Holding Ponds, Wells, In-ground / Above Ground Tanks and with Inventory Tank Gauging.

Ranges from 0-40"WC thru 15 'WC have combined accuracy of +/- .50% FSO

Ranges greater than 15' WC have combined accuracy of +/- .35% FSO

Viatran also offers a complete range of accessories for use in level applications such as a surge protector, cable hangers and weights, meters and junction boxes.

Replacement sensor heads and/or cables can be purchased separately
