||Integral R.F. Capacitance Level Transmitter
- Self-contained integral electronics
- Explosion proof design
- Isolated 4-20mA and 0-10 Volts DC output
- Simple two-step calibration
- Universal power supplies
- Built-in static suppression
Delavan's Cap Analog 410 is a completely adjustable Integral R.F. Capacitance Transmitter. The 410 system provides a continuous 4-20mA analog signal proportional to the level. This versatile transmitter can be used in liquids, slurries and most powder bulk solid applications.
Principle of Operation
Delavan's R.F. Capacitance Cap Analog 410 system consists of an electronic amplifier mounted in a cast aluminum explosion proof housing. The housing is integrally mounted on the top of the probe.
The Cap Analog 410, along with its probe sensor, operates as a capacitance sensitive system that converts changes in level to changes in output signal. After calibration, any change in level is recognized and converted to an analog output signal (4-20mA or 0-10 Volts DC). The system will operate any standard 4-20mA DC or 0-10 Volts DC indicator. The Delavan AFI-150 or DFI-150 indicator is available mounted in a rugged NEMA 4X housing.
The Cap Analog 410 is supplied with two 20 turn, (ZERO and SPAN) potentiometer adjustments. These controls are independent and non-interacting. In addition, DIP switches are provided to extend the range of ZERO and SPAN potentiometers.
