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
• Consult Vishay for other lead length
