What is Hart in pressure transmitter?
HART functionality enables the transfer of pressure transmitter data via an AC digital signal which uses the 4-20mA analogue output signal as a carrier, thus eliminating the need for extra wires and connectors.
How does a submersible pressure transducer work?
Submersible level transmitters consist of a sensor attached to a long cable, which is then lowered to the bottom of the liquid vessel. The sensor operates by measuring the hydrostatic pressure of the liquid medium. Also known as the head pressure, hydrostatic pressure is the pressure exerted by the fluid in the vessel.
How does a pressure level transmitter work?
A differential pressure transmitter calculates level by measuring the differential pressure between the liquid and the gaseous phases of the fluid inside a closed tank. For precise calculations, important factors include: Geometry of the tank (horizontal or vertical, shapes of various lids and bottoms, etc.)
Why do we use pressure transmitter?
A pressure transmitter is a device that has been designed to measure pressure in liquids, fluids or gases. They are commonly used to measure pressure inside industrial machinery, in order to alert users before an incident occurs. They have a wide range of different uses, mostly of an industrial or automotive nature.
What is the purpose of HART?
HART (Highway Addressable Remote Transducer) Protocol is an open standard used globally to send and receive digital information using analog wiring between smart devices and control systems. With over 30 million devices installed, it is the most popular protocol used in the field.
What is HART configuration?
The HART Protocol provides two simultaneous communication channels: the 4-20mA analog signal and a digital signal. Together, the two communication channels provide a low-cost and very robust complete field communication solution that is easy to use and configure.
What is a submersible pressure transmitter?
A submersible pressure transmitter is a pressure transmitter used especially for level measurement and designed to be completely submerged in a fluid.
How many types of level transmitters are there?
There are six main types of level transmitters. Each of these transmitters work in different ways, making them useful for a number of different types of processes. BM Engineering provide a range of different types of level transmitters from Bürkert including radar, ultrasonic and guided microwave.
