The sensor is sometimes part of the instrument assembly, as with some pressure instruments, but is more often separate, as with analytical instruments, such as those used for pH measurement. Before ...

Test equipment starts with an accurate pressure source to simulate the transmitter input. The corresponding output is measured with a multimeter for a 4–20 mA transmitter, or with a specialized device ...

differential pressure and static pressure while efficiently delivering the diagnostic information to these devices. The Smart Multivariable Transmitter (SMV) system is built based on the Thermo ...
