Smart pressure transmitter measures pressure in various mediums (liquids, fluids, gases) and is designed for pressure monitoring and control applications. The transmitter signal output is in the form of current (4 to 20 mA) with digital communication protocol (HART). It offers configurations for gauge pressure, absolute pressure and differential pressure.
Types of Pressure:
- Gauge Pressure: The pressure which is measured above atmospheric pressure. Examples of industrial applications: open tank level, line pressure, blanket pressure in a tank.
- Absolute Pressure: The pressure which is measured above vacuum. Examples of industrial applications: open tank level, line pressure, blanket pressure in a wet/dry tank, plant atmospheric reference.
- Differential Pressure: Difference between two applied pressures points. Example of industrial applications: closed tank level, density, filter health, DP flow.
Process Connection:
- Threaded: The seal utilizes a male or female NPT to make a direct connection with a process.
- Flanged: Flanges are available in various types such as flat face, raised face, or ring joint flange.
- Sanitary: Connections are ideal for applications that demand high hygiene. These connections must comply with Clean in Place (CIP) methodologies as well as FDA requirements.
Accessories
- Capillary: A capillary is connected between the diaphragm seal and pressure measuring instrument to eliminate or to minimise temperature effects from the hot fluid to the measuring instrument. In some cases, remote mounting with the capillary is used for hazardous or hard-to-reach location.
- Cooling towers: Cooling towers are intended to protect the instrument from excessively high process medium temperatures. Recommended for process temperatures +100˚C.
