MODEL XMT-C SECTION 1.0 DESCRIPTION AND SPECIFICATIONS 1.6 HART COMMUNICATIONS 1.6.1 OVERVIEW OF HART COMMUNICATION HART (highway addressable remote transducer) is a digital communication system in which two frequencies are superimposed on the 4 to 20 mA output signal from the transmitter. A 1200 Hz sine wave represents the digit 1, and a 2400 Hz sine wave represents the digit 0. Because the average value of a sine wave is zero, the digital signal adds no dc component to the analog signal.

MODEL XMT-C SECTION 11.0 THEORY OF OPERATION SECTION 11.0 THEORY OF OPERATION 11.1 CONDUCTIVITY / RESISTIVITY / % CONCENTRATION Liquids can only conduct electrical currents when they contain particles that carry charges. These particles are called ions, and they are produced when acids, bases, and salts are mixed with water. The conductivity of a substance determines how well it can carry electrical currents and is used to indicate the concentration of acids, bases, and salts in water.
MODEL XMT-C SECTION 11.0 THEORY OF OPERATION DEFINITIONS 1. LINEAR TEMPERATURE COEFFICENT OR TEMPERATURE SLOPE. The change in the conductivity of most electrolyte solutions having conductivity greater than about 5 mS/cm at 25°C can be expressed by the following equation: C25 = Ct 1 + a(t- 25) In the equation, C25 is the conductivity at 25°C, Ct is the conductivity at t°C, and a is the linear temperature coefficent.
