Stick. Safe Tank level Indicator Control Kit

Teklab’s STICK (Safe Tank Indicator Control Kit) is suitable where visual indication and/or control of the level inside a tank/vessel is needed.

The unit comprises electro-optic sensors which have bodies made of stainless steel and dome made of glass: having no moving parts the reliability of the control is very high (SAFE).

The units are customizable selecting the number of levels and the positions where the levels will be mounted.

Also the kind of control is customizable

Sensors with or without LEDs on their back
Sensors with or without output wire (level switch function)
Possibility of having a compact and cheap control unit that collect the sensors output and gives the required output type (4-20mA, Serial data over RS-485 or other protocols, ets)

Leds on the back of the level sensors are available for applications where visive info of the level is required (INDICATOR Feature).

The output wire is useful for interfacing the unit to external control or give an alarm (eventualy with a simple external relay) for low or high level condition (CONTROL Feature).
The pipe can be terminated with fl anges or welding valves for easy installation
