1 Scope

In addition to the requirements specified in GB/T 18268.1, this part of GB/T 18268 specifies, in more detail, with integrated or remote signal conditioning Transmitter 's test configuration, operating conditions and performance criteria.

This section applies only to transform functions and, with the assistance of auxiliary energy, convert non-electric quantities into process-related electrical signals and A transmitter that outputs a signal on one or more ports. This section contains transmitters that measure the amount of electricity and biomass.

The transmitters referred to in this section may be powered by AC or DC voltage and/or batteries, or have internal power supply.

The transmitter described in this section consists at least the following parts (see Figure 101 and Figure 102).

- one or more elements that convert non-electrical inputs into electricity;

- transmitting the power to the transmission link of the signal conditioning element;

- a signal conditioning unit that converts power into a process-related electrical signal;

A case in which the above elements are enclosed in whole or in part.

The transmitter described in this section may also include the following items (see Figure 101 and Figure 102).

--- a communication and control unit;

--- a display unit;

--- control components, such as keys, buttons, switches and so on;

--- Clearly used as input signal transmitter output signal (for example. switch signal, alarm signal);

--- with integrated or remote signal conditioning transmitter.

The manufacturer shall specify the intended use environment of the transmitter and select the appropriate test grade from the specification of GB/T 18268.1.

The appendix to this section gives additional requirements and exceptions for special transmitters.
