COMPONENT DESCRIPTIONS
The InterRanger is made up of three main components: the Monitor, the Transceiver, and the Sensor.
The Monitor
displays the current interface level and transmits this information to other equipment.
The Transceiver
drives the ultrasonic Sensor and transmits the echo signals to the Monitor.
The Sensor
sends out the ultrasonic pulses through the liquid medium and receives the echoes.

IR-200 MONITOR
Description
The Monitor is housed in a fiberglass NEMA 4X enclosure
containing the signal analysis, display, and control circuitry
for the system. All configuration and parameter changes are
made from the membrane keypad on the front panel of the
Monitor.
Temperature Range
-10°C to 50°C (14°F to 122°F)
-30°C to 50°C (-22°F to 122°F) with optional heater
Drawing
0-8130003Z-DU-C
HEATER FOR MONITOR
Description
The optional heater should be ordered when the Monitor is to
be located in a climate that drops below -10°C (14°F). The
heater has a built in thermostat so that power consumption is
kept to a minimum. When operating, the heater will consume
an additional 50 watts of power and is available in 115Vac
and 230Vac configurations.
IRP-8D TRANSCEIVER
Description
The Transceiver is housed in a polycarbonate NEMA 4X
enclosure and boosts the Sensor signal enabling it to be
transmitted over standard signal cable for up to 225 m (750’).
For use with the IRT-100D or IRT-100DC Sensor.
Temperature Range
-30°C to 50°C (-22°F to 122°F)

IRT-100D SENSOR
Description
A small, submersible, dual head Sensor constructed of
polyurethane and 316 stainless steel. It is fitted with a 3/4”
NPT nipple and includes 7.5 m (25’) of shielded cable
(optional 22.5 m (75’) available).
Temperature Range
-30°C to 80°C (-22°F to 176°F)
Drawing
0-8140001Z-DU-C
IRT-100DC SENSOR
Description
Same as the IRT-100D but is constructed of high
temperature epoxy. Supplied with either a Kynar®or 316
stainless steel 3/4” NPT nipple and 7.5 m (25’) of Teflon®
jacketed cable (optional 22.5 m (75’) available).
Temperature Range
-30°C to 105°C (-22°F to 221°F)

STATIONARY HANDRAIL BRACKET KIT FOR SENSOR
Description
This kit contains a two piece mounting bracket, two 2” U-bolts and two 3/4” U-bolts for suspending an IRT-100
series Sensor from a standard 2” handrail. The 3/4” pipe and coupling needed to connect the Sensor to the
bracket are supplied by the customer.

SWING OUT ADAPTOR KIT FOR SENSOR
Description
This kit contains a swing-out bracket, a skimmer
guard, and six 3/4” U-bolts for use with an IRT-
100 series Sensor and Stationary Handrail
Bracket. This kit should be used if the tank has a
surface skimmer so that the Sensor deflects out
of the way when the skimmer moves past it.

STORAGE
All components can be stored in a dry area with a maintained temperature range of -20°C to 50°C
(-4°F to 122°F). The Monitor and Transceiver should be sealed to prevent moisture intrusion in humid areas.
MAINTENANCE
The only part of the InterRanger IR-200 that requires maintenance is the Sensor face and only when it is
subject to algae or scale build-up.
Cleaning of the Sensor face is required is if build up of material exceeds:
»algae or debris: >1.5 cm (1/2”)
»scaling: >0.75 cm (1/4”)
Greater build-ups than these will make it difficult for the Sensor to detect the return echo signal and may result
in incorrect or null readings. The timing of this maintenance is determined by the rate of accumulation and
should be estimated at the installation site.
There is no routine maintenance or calibration procedures that need to be performed on the IR-200
electronics.
