Level Transmitter


Sitron's Capacitive level probes are primarily used for level measurement and control in various industrial processes. They can be applied in conductive and non conductive media such as water, oil, solids, pastes, chemicals, among others. The probes can also be used to detect the interface between liquids (oil / water). Like all Sitron products the capacitive probes can be produced in a variety of threaded, flange or sanitary connections.

Ultrasonic level meters are compact measuring devices that contain an ultrasonic transmitter and an electronic module. The transducer generates ultrasonic pulses that travel at the speed of sound toward the target medium. These sound waves are reflected on the surface of the medium and are received by the transducer system.
Based on the time period the distance or height of the medium is calculated by the electronic block (which also performs temperature compensation) and subsequently converted to an output current 4 ... 20mA with HART, voltage 0 ... 10 V or RS-485 output Modbus.
The meters are applied for monitoring and level control of liquids and solids without being in direct contact with the medium.
Models and features:
SLU - Quick display of the measured values ​​in the display / Easy adjustment without being in contact with the measuring medium / Mapping of false echoes / Possibility of use in explosive zones (version X) / Current output (4 ... 20mA) with HART® protocol or RS-485 Modbus output MSLU - Level adjustment via 2 buttons or magnetic pen / Version X for Explosive Areas / LEDs to indicate meter status / Output current (4 ... 20mA), voltage output (0 ... 10 V) or RS output -485 Modbus / Fast connection via connector
