Product Description
National Controls' panel mount thermometer allows the
constant monitoring of temperature in critical environments and
equipment, enabling a higher degree of operating efficiency.
The high temperature alarm alerts personnel to a high
temperature condition, protecting temperature sensitive
equipment and operations. When the temperature rises to the
setpoint temperature, the display flashes and an audible alarm
sounds. When the temperature falls below the setpoint
temperature, the alarm condition ceases. If during the alarm
condition, it is desired to turn off the alarm, depressing the
front panel push-button will interrupt the audible alarm for
approximately 2-1/2 hours, but the display will continue to
flash.
The heavy-duty stainless steel front plate protects the unit
from mechanical shock and abuse, and is designed to blend
visually with other stainless steel equipment.
The thermometer can be mounted directly on the
equipment it is monitoring, or on a remote panel up to 250 feet
away.
The thermometer is powered from low voltage AC or DC,
thus eliminating the high costs of installation to NEC or other
high voltage electrical standard wiring.
The control can also detect an open or shorted
temperature probe. If the probe is open or shorted the display
will show "Prb", the alarm will sound and the relay contacts will
close. The alarm will continue to sound until the probe error
condition is corrected. In addition, the output relay's contacts
will close during a high temperature ALARM condition.
Setting the High Temperature Alarm:
On the front of the TM165 and TM166 there are up and down
arrow buttons for changing the set point temperature. The set
point can be adjusted to any temperature within the specified
range of that particular model.
Setting ºF or ºC Operation:
Using the front panel buttons the display can be adjusted
to
display temperature in ºF or ºC.
