What are the main advantages of Rosemount temperature transmitters?
1. Only by adapting to harsh environments can it be strong
Rosemount temperature transmitters generally work in a wide range of environments, from extremely cold to very hot areas, many of them work in the open air, to be able to resist flying sand, dust, but also to resist moisture, high resistance to salt corrosion, acid corrosion, anti-polluting gas interference, to adapt to the extreme cold, high temperature, strong vibration, impact and other conditions of normal work, but also to strong noise resistance, high signal-to-noise ratio.
2. The price is moderate, suitable for mass production
Rosemount temperature transmitters are consistent and suitable for automated mass production, and have high requirements for processing equipment to eliminate inconsistencies and errors caused by manual operations.
3. High stability and reliability
There are a lot of Rosemount temperature transmitters due to the use of environmental conditions need to use metal for packaging, so generally the selection of welding sealing, this kind of Rosemount temperature transmitter has sensitive components and integrated circuits inside, inert gas or vacuum isolation from the outside world, there are pressure resistance, air tightness requirements, as well as welding strength requirements and air leakage rate requirements, the welding quality requirements are also relatively high, and the welding process requires that the deformation is relatively small, can not form damage to internal components and microcircuits.

A method for verifying a current loop signal for a Rosemount pressure transmitter
The Rosemount pressure transmitter uses a 4-20mA signal, which is the conversion value of the output generated by the pressure transmitter. The output of the transmitter is detected according to the HART protocol, however, it is converted to a proportional current so that it can be visualized as a reading. Normally, at zero level output, the transmitter displays 4mA ...
