Hydrostatic Pressure Level Transmitter
ECX
The ECX hydrostatic pressure level transmitter uses piezoresistive technology and a Wheatstone bridge circuit to measure the level of liquids in various tanks and other types of vessels and provide a variable 4-20mA output.
The ECX hydrostatic pressure level transmitter consists of a piezo resistive sensor. The Wheatstone bridge directly measures head pressure exerted on the diaphragm of the EC level transmitter.
When the pressure is exerted on the diaphragm, as a result of the liquid level. The pressure is transferred to the Wheatstone bridge electrical circuit through silicon oil contained in the EC sensing unit. This creates a differential voltage, which is then amplified to create a variable 4-20mA output that varies as a result of the changing liquid level.
In addition, a pressure transducer is available for measuring pressure in tanks or pipes and producing a variable 4-20mA output.
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.
USE
- Extension cable unit can measure deep wells or reservoirs
- Tank level measurement and control
- PLC or DCS input for level control functions
- Pressure measurement of gas or liquid (EC1500)
- EC1100 is a liquid measurement device which can be used in a variety of environments, including water agitation environments.
