ECX Hydrostatic Pressure

Level Transmitter

The ECX Hydrostatic pressure level transmitter is used for measuring the level of liquids in various tanks and other types of vessels. The ECX hydrostatic pressure level transmitter consists of a piezo resistive sensor and Wheatstone bridge to directly measure 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.

  • 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.
  • The Standard Flange Type, EC1210 can be used in liquid & gas pressure measurement environments (i.e., mildly corrosive environments).
  • EC1300~1320 type is suitable for measurement of very deep water, such as measurement of reservoirs.
  • EC1500 is suitable for pressure measurement or control devices such as those found in hydraulic and pneumatic machines.
  • EC1200 can withstand high temperature liquid environment.
