Stork Analogue Submersible Water Level Sensor, 0-5MWG, 4-20mA, 2-Wire, G1/4″
The SLS range of underwater level sensors has been developed using a durable stainless steel housing that encloses an isolated diaphragm silicon piezo-resistive sensing element. This design allows the submersible level transmitter sensors to withstand depths of up to 100 meters when fully submerged in liquids, ensuring continuous operation.
These water level sensors come with two options for output. The first option is a raw millivolt output, which is ideal for applications requiring low power consumption. Alternatively, the sensors can be equipped with an internal microprocessor that provides an amplified output, such as 4-20mA, 0-10V, or 0.5 to 4.5V ratiometric signals.
The integrated 16-bit microprocessor on board the sensors enables advanced features like high-level linearization, temperature compensation, and calibration. These capabilities ensure that the sensors deliver exceptional accuracy, stability, and repeatability, making them suitable for demanding applications such as environmental monitoring, flood defence systems, and measuring water levels in rivers, reservoirs, and boreholes.
