NTC Thermistors, Miniature Immersion Sensor

Note

• Other R

values and tolerances available upon request

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

• Consult Vishay for other lead length
