16 IOM-DPT-A: FEB 2014 6.2.1. Transmitter casing A casing of DPT... transmitter is made of high-pressure casting of aluminium alloy or 316L steel. It consists of a body, two bolted side covers (full and with pane), cable inlets and plug with M20x1,5 or ½ NPT thread. Inside the casings is divided into two chambers, separated by a header. An additional header, with a ribbon cable is intended for transmitting a signal from temperature sensor to the inside of a transmitter.
17 IOM-DPT-A: FEB 2014 8.3. Protection from excess voltage 8.3.1. The transmitters may be in danger from excess voltage caused by connection faults or atmospheric electrical discharge. Protection from excess voltage between the wires of the transmission line is provided by TVS diodes installed in all types of transmitter (see the table, column 2). 8.3.2.
18 IOM-DPT-A: FEB 2014 9.2. Configuration and Calibration 9.2.1. The transmitter has features which enable metrological and identification parameters to be set and altered. The configurable metrological parameters affecting the transmitter’s output current include the following: a. lower end-point of the set range b. upper end-point of the set range c. unit d. time constant e. type of characteristic curve: linear or radical f. decimal index 9.2.2.
