Sensor Mounting Guidelines - Refrigerator Applications
The Elpas Internal Thermistor - Temperature Sensor (P/N: 5-STE00433-1) is
suitable for general purpose refrigerator applications (such as food and
pharmaceutical storage) where ambient temperature monitoring is sufficient.
Use an Elpas Mounting Clip (P/N: 5-ETC09001) with an ultra-high bound adhesive
to mount the temperature sensor on the side wall as close to the middle of the
refrigerator as possible. Avoid mounting the temperature sensor near or in the direct
air path of cold air intake since there will may be wide temperature swings at this
location. If the refrigerator is relatively empty consider adding bottles of water or other items to help stabilize the temperature
of the refrigerator.
The Elpas External Probe - Temperature Sensor (P/N: STC00433-1) is for refrigerator applications (such
as blood, vaccines and pathology storage) where it is necessary to immerse the probe in propylene glycol to
better match the thermal properties of the items being stored. Mount the probe and glycol bottle on the side
or back corner of the refrigerator where it will not be disturbed, while placing the sensor’s electronics either
inside or outside the refrigerator. Use tape or tie-wraps to secure the probe cable to the side wall or shelf.
Sensor Mounting - Freezer Applications
The Elpas External Probe - Temperature Sensor (P/N: STC00433-1) is also for
freezer applications below -20°C/4°F where placement is limited by the operating
limits of the sensor’s electronics and battery. The sensor’s remote probe enables
temperature measurements inside the freezer while its electronics and battery is
mounted externally on the outside of the freezer. The probe can be attached to a
shelf or other bracket using tie-wraps. Avoid the cold air intake and try not to mount
it on the top of the freezer as this area can become warm during defrost cycles, In
relatively empty freezers add bottles of frozen water or ice packs to help stabilize
the temperature of the freezer.
Cleaning Procedures
Use an appropriate antibacterial disinfectant such as Dispatch® Hospital Cleaner Disinfectant with Bleach from Caltech
Industries (http://www.caltechind.com) to clean the Elpas Temperature Sensors.
Since ‘Cleaning Procedures’ may vary according to facility guidelines, thus the procedures given below are for illustrative
purposes only:
Option 1 – Using Dispatch Disinfectant Spray
1. Lightly wet a disposable towel with Dispatch spray
2. Do not saturate the towel
3. Wipe the outer surfaces of the sensor
4. Next wipe the sensor with a dry disposable towel
5. Allow the sensor to air dry
6. Return the clean sensor to inventory or usage
7. Dispose of used towels per facility policies
Option 2 – Using Dispatch Disinfectant Towels
1. Open a new Dispatch pre-moistened towel
2. Wipe the outer surfaces of the sensor
3. Next wipe the sensor with a dry disposable
towel
4. Allow the sensor to air dry
5. Return the clean sensor to inventory or usage
6. Dispose of used towels per facility policies
