Geography hydrocarbon production is expanding, and with it the level of technical equipment industry. Currently on the market there are more modern temperature sensors. This type of sensor is designed to measure the temperature of liquids and gases by converting the signal from the sensor to the transmitter in a unified current signal and a digital signal. Temperature sensors consist of a primary converter temperature - sensor connected to the measuring conversion. Measuring the conversion is structurally positioned thereon with terminals for connecting the sensor and terminals for outputting an output signal. Power transmitter combined with the output of a two-wire circuit. Measuring conversion may be integrated in the connection head of the sensor, or have its own protective casing, or be placed in a protective valve head with protective or other mounting devices for connecting with the transmitter. The sensor may be a single or double. To measure the temperature at high pressures and flow rates provided protective sleeve design which depends on the parameters of the medium permitted. Working temperature sensors is based on the conversion of the sensor signal into a standardized output signal of DC superimposed on its digital frequency-modulated signals in either standard output signal with a digital protocol. Since the sensor signal input to the transmitter where it is converted via the inverter microprocessor. The output of the microprocessor digital signal converter is supplied to the digital modulator protocol.
