The leading edge microprocessor-based instrument includes display and full keypad for ease of calibration and set up. Literature Select Your LanguageUS English Additional Tools:            Measurement Principle: As the media rises and falls in the tank, the amount of capacitance developed between the probe and the ground reference changes. The electronics convert the change in level into an isolated 4-20 mA analog output signal. Features: Two or four relays Optional intrinsically safe probe circuitry 16-button keypad 2 by 16 LCD display Powerful self-diagnostics check the system Small change in level required for calibration Applications: Continuous level measurement Interface measurement Hydrocarbon and solvents Slurries Acids High temperature/pressure liquids Options: Input power Relays Integral or remote electronics Probe selection
