1 OVERVIEW

1.1 General Overview

Plug & Test® sensors accommodate numerous force and torque measurement requirements, from 0.25 to
10,000 lbF (1 N to 50 kN) of force, and from 10 ozFin to 5,000 lbFin (7 Ncm to 550 Nm) of torque. These
sensors can be handheld or mounted to a fixture or test stand for more sophisticated testing
requirements.

Plug & Test® sensors are used with Mark-10 7i, 5i, and 3i indicators. They may be disconnected from one
indicator and connected to another without the need for re-calibration or re-configuration. All such data is
saved within a PCB located inside the smart connector.

The model number, serial number, and capacity of the sensor are identified in the rectangular label
located on the connector. The model and serial numbers are also identified in the Information screen of
the indicator. Refer to the indicator user’s guides for more information.

1.2 Accuracy and Resolution

Indicator accuracy must be combined with sensor accuracy to determine the total accuracy of the system.
Since sensors may be used with the 7i, 5i or 3i indicators, the accuracy of the indicator being used must
be identified and taken into account, as follows:

Indicator Model

Accuracy

7i / 5i

±0.1% of full scale

3i

±0.2% of full scale

The total system accuracy can be calculated by adding the sensor accuracy and indicator accuracy.
Refer to the following examples:

Example 1

Model MR01-100 sensor with Model 5i Indicator

MR01-100

±0.15% of full scale

+

5i

±0.1% of full scale

=

Total

±0.25% of full scale

This translates into a fixed error of up to:

0.25% x 100 lbF = 0.25 lbF
Example 2

Model MR50-50Z sensor with Model 3i Indicator

MR50-50Z

±0.35% of full scale

+

3i

±0.2% of full scale

=

Total

±0.55% of full scale

This translates into a fixed error of up to:

0.55% x 50 ozFin = 0.275 ozFin

Because accuracy is defined as a percentage of full scale, the fixed error is possible anywhere on the
scale from 0 to the capacity. As such, this value represents an increasingly large error as percentage of
reading towards the low end of the scale. It is, therefore, recommended that a sensor is selected with
capacity as close as possible to the expected load.

The resolution may be different for some sensors depending on whether a 7i, 5i, or 3i indicator is being

3

used. For example, a Series R01 force sensor will display finer resolution when connected to a 5i
indicator than when connected to a 3i indicator. Resolution information is shown in the following sections.

2 SAFETY / PROPER USAGE

Read through the following safety instructions thoroughly before using a sensor:

1. Note the sensor’s capacity before use and ensure that the capacity is not exceeded. Producing a
load greater than the indicated safe overload value can damage the sensor. An overload can
occur whether the sensor’s indicator is powered on or off.

2. In order to extend the life of the sensor, avoid repetitive shock and impact loading.

3. When moving the sensor to another location, never lift from the cable or strain relief. This can
cause damage to the sensor. Always lift the sensor housing itself.

4. Always ensure that load is applied axially with respect to the sensor.

5. Ensure that the sensor is kept away from water or any other electrically conductive liquids at all
times.

6. The sensor and indicator should be serviced by a trained technician only. AC power must be
disconnected and the indicator must be powered off before the housing is opened.

7. Always consider the characteristics of the sample being tested before initiating a test. A risk
assessment should be carried out beforehand to ensure that all safety measures have been
addressed and implemented.

8. Typical materials able to be tested include many manufactured items, such as springs, electronic
components, fasteners, caps, films, mechanical assemblies, and many others. Items that should
not be used with the sensor include potentially flammable substances or products, items that can
shatter in an unsafe manner, and any other components that can present an exceedingly
hazardous situation when acted upon by a force. Always wear eye and face protection when
testing, especially in aforementioned hazardous cases. Extra bodily protection should be worn if a
destructive failure of a test sample is possible.

9. In aforementioned hazardous situations, it is strongly recommended that a machine guarding
system be employed to protect the operator and others in the vicinity from shards or debris.

10. Sensors have threaded holes or chucks, designed for the mounting of grips, fixtures, or
attachments. If any such accessories are used, ensure they are mounted firmly to prevent a
potential safety risk to the operator and others in the vicinity. If using an accessory from a supplier
other than Mark-10, ensure that it is constructed of suitably rugged materials and components.
Similar precautions should be taken when mounting the sensor to a test stand, work bench, or
other piece of equipment.

10 SERIES R50 TORQUE SENSORS

10.1 Unpacking and Assembly

Carefully remove the sensor from the box. For models MR50-10Z,
MR50-20Z, and MR50-50Z, remove the protective tubing inserted
around the chuck. Save it for future transportation needs. No
assembly is required.

10.2 Overview

Designed for clockwise and counter-clockwise torque testing. The
sensor may be handheld or mounted to a test stand, fixture, or other equipment. Bits or fixtures may be
placed in the chuck, although extra care should be taken when handling low capacity models.

10.3 Specifications

Accuracy: ±0.35% of full scale
Safe overload: MR50-10Z - MR50-50Z: 300% of full scale

MR50-12 - MR50-100: 150% of full scale

Chuck opening range: MR50-10Z - MR50-50Z: 0.062 - 0.375 in [1.6 - 9.5 mm]

MR50-12 - MR50-100: 0.078 - 0.5 in [2.0 - 12.7 mm]
Operating temperature: 40ºF – 100ºF [5ºC – 38ºC]
Operating humidity: 96% max. (non-condensing)
Weight: From 1.4 lb [0.6 kg]

10.4 Calibration
Calibration should be performed in a vertical orientation, especially for sensors with capacities of 50 ozFin
[35 Ncm] or less. Horizontal orientation subjects the sensor to side loads resulting from the weight of the
chuck and attachments. Such side loads can be significant enough to skew the readings out of tolerance.

The illustration below depicts a recommended vertical setup:

For further calibration instructions, refer to the indicator’s user’s guide.
