PULSAFEEDER Microtrac Series Controllers

The MICROtrac is a microprocessor based feed and bleed toroidal conductivity controller
designed to control conductivity and feed inhibitor in cooling tower systems. Featuring
innovative toroidal sensor technology, the MICROtrac provides an economical control
platform that is not susceptible to sensor fouling and never requires calibration!
Principle Operation:
The MICROtrac measures the conductivity of the cooling tower recirculating water
via a toroidal conductivity sensor. The controller activates two independent relay
outputs based on a bleed and feed mode of operation. When the conductivity measurement
goes above the user defined set point, the two relays are activated until the conductivity
drops below the set point and the fixed differential value, or until the user programmable
limit times for feed or bleed are exceeded.

Operation Benefits:
- No Calibration Required! - MICROtrac's toroidal sensor technology saves you valuable
service time and money by eliminating routine calibrations. The MICROtrac toroidal
conductivity sensor is factory calibrated for the life of the probe.
- Reduced Potential for Fouling! - By design, the MICROtrac toroidal conductivity
sensor has no exposed electrodes, which means that there is nothing to wear out
or foul. When installed according to the manufacturer's instructions, the need for
routine sensor removal and cleaning is virtually eliminated – saving you time and
money.
- Two Year Warranty on Controller and Sensor - You can install the MICROtrac controller
with confidence, knowing that it is backed by Pulsafeeder with a two year warranty
on the controller and probe.
- Large Range - The MICROtrac conductivity controller has a 0-9,999 µS/cm range, making
it ideal for other applications as well, such as rinse, industrial process, wastewater,
etc.
- Simple User Interface - A large LCD display and simple programming via a three-button
interface make the unit extremely easy to set up and program. With no calibration
required and a fixed differential, all that needs to be done is to program a conductivity
set point and, if desired, the limit times for the feed and bleed relays.
- Easy Installation - Optional pre-wired receptacles for the relays and an optional
pre-wired flow switch make installation a breeze.
