Digital ES II Modulevel® – Electronic Liquid Level Transmitters
Digital ES II electronic transmitters are advanced, intrinsically safe two-wire instruments. In addition to the standard 4-20 mA output, the Digital ES II is equipped with microprocessor-based electronics and HART® compatible output.
Measurement Principle : As process liquid level moves, the buoyancy force changes on a displacer suspended from a range spring. The change in force causes the spring to expand or contract, moving the core within an LVDT. This change of position is translated to a digital output.
Features :
- HART network compatible
- Remote calibration without level movement
- Standard output range from 3.8 to 20.5 mA
- Push-button program local calibration
- Continuous self-test
- Signal sampling 15 times per second
Applications :
- Feedwater heaters
- Scrubbers
- Receivers
- Separators
- Interface level
- Knock-out drums
Options :
- Flanged top or external cage mounting
- Hand held communicator
- Analog or digital display
- Electronics integral or remote mounted
- Steel or 316 stainless steel chamber material
