1. Introduction
The Wahl R10 compact infrared sensors are non-contact infrared temperature measurement sensors.
They are designed to measure the infrared radiation emitted from an object, and convert it to an
electrical signal. This signal can then be processed to determine the surface temperature of the
measured object. The R10 series are all fixed emissivity at 0.95 ±0.2. All models require a 7-24V DC
power supply @ 25mA current.
Standard supply includes a 5’ (1.5m) shielded cable with an option for 10’ (3m) cable. Two M18x1mm
mounting nuts are also provided. The 4-20mA output model requires only 2 wire connections while the
mV and t/c output models use 4 wire connections, 2 for power and 2 for output signal.

5. Optical Chart
The R10 optical field of view is nominally 20:1 D:S ratio. D:S ratio is an abbreviation for Distance to Spot
ratio. For the R10, for every 20 units of measure distance, the target diameter that the R10 is measuring
will be 1 unit. For example at a distance of 20 inches the unit will be measuring a 1” diameter target and
at 60 inches it will be measuring a 3” diameter target. The minimum diameter is approximately .35
inches (8.9mm).

Installation consists of 4 primary steps: Mechanical, Environmental, Wiring Installation and
Validation/Operation
6.1. Mechanical
Pyrometer placement - The mechanical process starts with determining the proper mounting
location. One key factor of this is the D:S ratio of the instrument used. The placement has to
allow for proper filling of the field of view. The below diagram demonstrates proper target
filling. Failure to completely fill the target area of the pyrometer will result in increased error of
the measurement. The dotted circle indicates the field of view.
Palmer Wahl offers various mounting brackets as listed in Section 3, which offer various
adjustment methods. Additionally, the unit can be mounted in an 18.2mm diameter hole with
the included mounting nuts.
6.2. Environmental Considerations
Conditions such as ambient temperature, atmospheric particulates and electrical interference
should be considered.
6.2.1. Ambient Temperature
The unit is designed for operation in ambient temperatures from 0° to 70°C (32° to
158°F). Temperatures above 50°C will require a cooling jacket, which can extend the
temperature range as high as 200°C (392°F) with water cooling.
6.2.2. Atmospheric conditions
Atmospheric conditions fall into two main categories. The first is for particulates or
materials in the optical path that may interfere with the measurement. This can be
things such as trying to measure through a window or screen or an excessive amount of
particulates such as dust, fibers, fumes or smoke particles in the air. These all have the
potential to induce error in the measurement. The second category is for these
airborne contaminants to settle on the lens and coat the lens which will reduce the IR
energy getting to the detector. These type of contaminants may be controlled by using
the air purge collar which creates a positive flow of clean, dry air out through the front
opening to prevent contaminants from entering the housing and adhering to the lens.
6.2.3. Electrical Interference

6
Excessive electromagnetic interference may induce error into the measurement. To reduce the
possibility of this happening, do not place the unit near electrical equipment that generates
large amounts of EMI. These are usually apparatus such as motors, switches, controllers and RF
transmitters/antennas.
Connecting the shield of the cable to an earth ground may also help reduce any effects from
EMI.
6.3. Wiring Installation
Connect the wiring per the following table. The wiring color code is also printed on the unit’s
label. Wiring should be in accordance with any applicable Federal, State and Local codes.
There are additional wires that are enclosed in heat shrink which should not be connected as
these are for factory calibration only. Standard delivery includes a 5 foot cable with an option
for a 10 foot cable. In most cases the wiring can be extended by the user, by a skilled
electronic/electrical technician using proper connection and grounding techniques.
The power supply requirements are 7-24V DC power. The R10A with 4-20mA output requires a
25mA power supply, while the R10J, K, V models require a10mA power supply.

7. Validation/Operation
After installation the measurements should be validated. This will verify that the optical path
and materials are compatible with this instrument. To validate the system requires a target of a
known temperature. This can be from the temperature controls, an independent
mechanical/electronic thermometer, or another infrared thermometer, such as a handheld
infrared thermometer. This measurement should be compared to the R10 measurement and
should be within the specified tolerances of both temperature measurement systems.
In the event that there are inaccuracies due to differences in emissivity of the target, you may
be able to apply a correction factor as compensation.
The output for the R10A is a 4-20mA output scaled over the 0 to 500°C range. This equates to
32µA per °C or 17.78 µA per °F.
There are no under/over range indicators so at temperatures below 0°C the unit will always
output approximately 4mA and temperatures above 500°C it will always output approximately
20mA.

8. Important Notes:
When a sensor is first powered up it may take 10-20 minutes for the reading to stabilize.
If the sensor is subjected to rapid changes in ambient temperature, such as going from a cold to hot or
hot to cold area, it may require a 20 to 30 minute stabilization time.
Measurements made at high target temperatures for a 20 minute or greater time, and then rapidly
reduced may require a 2-10 minute settling time for the measurement to be within the specified
accuracy.
Incorrect wiring may result in permanent damage to the sensor and void the warranty.
9. Maintenance and Troubleshooting
9.1. Maintenance
Housing – The housing is constructed of AISI 304 Stainless Steel and should not require any
cleaning. If it does get dirty, cleaning should be with a damp cloth and mild detergent.
Lens – The lens must be kept clean at all times. If the air purge collar is not used the lens may
need to cleaned with clean compressed air or a moist cotton swab to gently wipe off the lens. A
dry cotton swab may be used to remove any moisture left on the lens. DO NOT use solvents on
the lens!
Wiring – make sure the wiring is protected and not subject to crushing, cutting or extremely
tight bending.
9.2. Trouble shooting
See the below chart for troubleshooting tips. If the problem is not remedied, call Palmer Wahl
customer service at the number provided at the end of this manual for a Return Material
Authorization (RMA) number prior to returning any goods.
