PURPOSE
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.
