The PD 940 Dipstick is a hygienic electronic level sensor for electrically conductive liquid. In addition to level, it also measures the conductivity and temperature of the liquid.
A fast reacting temperature sensor is mounted in the tip of the dipstick
The dipstick is well suited for use in air eliminators, where there is often a lot of foam on top of the liquid, as the level signal includes only the equivalent liquid of the foam.
The level measurement is independent of the liquid conductivity, so the dipstick is self-calibrating and can be used with different liquids without any re-calibration.
The PD 940 Dipstick is mounted on the vessel using a clamp connection, with a special flange welded onto the vessel.
The minimum distance from the dipstick (including the tip) to the tank is 50 mm. The tip must be fully submerged in liquid to get an accurate measurement.
The dipstick can be used as a sensor where the level is represented an analogue output (4-20 mA) or it can communicate level, conductivity and temperature with the control system via a standard P-NET RS485 interface.
The dipstick includes a digital I/O which can be setup to e.g. control a pump in the measurement system, depending on the measured level.
The dipstick is programmable in COPP, which means that a part of, or complete automation application can run in the dipstick.
The program can make use of ready-made components to control and monitor any process – or machine application, both locally in the dipstick and via the network interacting with other devices.
