NTC Thermistors, Miniature Immersion Sensor
DESIGN SUPPORT TOOLS AVAILABLE
Fig. 1 - Mounting example with sealing ring and screw
FEATURES
Fast time response for fluid immersion
applications
Reduced thermal gradient, due to the use of
small tip dimensions and thin insulated wire
Sensor for permanent contact with water or
other liquids
Material categorization: for definitions of
compliance please see www.vishay.com/doc?99912
APPLICATIONS
Immersion sensor used for temperature measurement,
sensing and control in:
Water boilers
Heating systems
Chiller systems
Water and used water systems
Water and oil tanks
Consumer appliances, Coffee machines
Industrial appliances
Solar heating systems
DESCRIPTION
Miniature insulated chip NTC thermistor mounted in a
SS304 housing with or without brass collar for sealed
mounting and twin PVC insulated AWG#30 lead wire
connection.
MOUNTING
The sensor can be mounted by means of a sealing O-ring
and screw
The end wire can be soldered, or crimped to a connector
Optional connector for Wire-to-Wire or Wire-to-Board
connections
The contact area with the liquid is preferably min 10 mm
down from the tip and max to the brass collar location (see
Fig. 1 for mounting example)
Not intended for corrosive or high acidic liquids
The epoxy lead-wire side can not be in permanent contact
with liquids, or water
PACKAGING
Available in plastic bags of 250 pieces.
DESIGN-IN SUPPORT
Other resistance curves and tolerances are available on
request
