The Pa993D SDI-12 submersible depth sensor is an intelligent microprocessor enhanced depth sensor designed for both level and temperature readings as standard. With its narrow diameter of just 23mm, it is ideal for V-notch weir flow measurement in open channel flow applications and environmental monitoring.
Thanks to its embedded 16-bit microprocessor-based electronics, the Pa993D SDI-12 submersible depth sensor can perform complex linearisation, temperature compensation and calibration to deliver extremely high accuracy of less than ±0.15% full scale, with an option to increase this to 0.1% or 0.06% if required, making them ideal for laboratory & research testing applications, environmental monitoring and flood defence systems.
The Pa993 is perfect for applications using battery or solar panels as it has a very low power consumption and can be powered from as low as 6V supply. Plus, it is extremely useful in multi-sensor setups as one or more SDI-12 submersible depth sensors can be used to interface with one datalogger.
They have a robust 316 stainless steel silicon sensing element coupled with a choice of Nitrile (NBR) or Viton (FKM), guaranteeing long term immersion protection to 100 metres. In addition, their moulded cable exit fitted with vented polyurethane (PUR) cable and strain wire provide a high integrity waterproof assembly as standard, making them ideal for the measurement of pressure within rivers, reservoirs and boreholes.
The Pa993D SDI-12 submersible depth sensor has a surge protection circuit to mitigate the effects of electrical transients caused by nearby lightning strikes and power supply fluctuations.
