A91 Series
Thermistor Temperature Sensors

For Duct, Immersion and Space Sensing


Application

These thermistor sensors are
used with Penn Series R93
electronic controllers to operate
Series M80J motor actuators
and/or Series R23 sequencers.
They are also used with Series
M40E and M40F motor
actuators.
The sensors are designed for
applications in the heating,
ventilating and air conditioning
industry. Immersion sensors
must not be used in liquids
injurious to the soft solder and
copper metals in the immersion
well.



Operation

When the sensor is wired to thecontroller it becomes part of a
voltage divider circuit, which
includes the set point
potentiometer. The voltage
divider output is used to position
the motor actuator or sequencer
in proportion to the temperature
deviation from the set point. If
the temperature at the sensor
changes, the resistance if the
element changes. This change
in the voltage divider is
electronically amplified and
causes the controlled device to
be proportionally repositioned.



Locating

Locate sensors where they are
exposed to the media being
controlled and where they sense
the average temperature of the
air or liquid being controlled.
Locate where temperature does
not exceed 140°F (60°C) or fall
below -40°F (-40°C).
Series A91 sensors are not
position sensitive and can be
mounted in any position.
