The PD 940 DIPSTICK is a solid state level sensor device.
The level in the vessel is measured as the part of the stick that is submerged in liquid.
In addition to the level sensor capability, the Dipstick also measures the temperature and the conductivity of the liquid.
The Dipstick communicates with the control system via a standard P-NET RS485 interface.
The Dipstick offers an analogue output (4-20 mA) which can be setup to transmit either the level or the conductivity. The digital output can be setup to e.g. control a pump in the measurement system.
The fast reacting temperature sensor is mounted at the very end of the Dipstick
The device is programmable in COPP, which means that a part of, or complete automation application can be built and downloaded by the user. The program can make use of ready-made components to control and monitor any process or machine application, both locally in the device but also via the network interacting with other devices.
The PD 940 Dipstick only works when mounted on a metal vessel. The foot flange on the Dipstick electronic housing must have good electrical connection to the vessel wall.
The electric connection is achieved by the clamp used to affix the Dipstick foot flange to the flange welded onto the vessel.
Both level and conductivity measurement depend on the shape of the vessel, the distance from the dipstick to the tank wall, the product temperature, and the electrical characteristics of the product. Recommended minimum distance from the tip to the tank: 50 mm.
Due to these dependencies both the level and conductivity have to be calibrated to the actual construction and the different liquids.
