TEMPERATURE - PROBES

Temperature Sensors - Probes

ES120 Series Coolant/Oil Temperature

Sensor Probes

The ES120 probe is a thermistor mounted into a plastic lead frame and

assembled into a metal body. This subassembly is then overmolded to

produce both the electrical connection system and the hexagonal shape

for easy installation. The all-plastic design reduces heat loss through the

sensor, thereby reducing wind chill effects.

Operating temperature range:

-40 °C to 155 °C [-40 °F to 311 °F]

Encapsulation:

NTC (Negative Temperature Coefficient) encapsulated

in thermal epoxy

Lead material:

Terminals are 2,8 mm x 0,8 mm [0.11 in x 0.03 in] brass

with a copper flash protection layer with final plating to

customer requirement (silver, tin, gold, etc.)

Dissipation constant:

Tor values (time to reach 63.2 % of the difference

between two temperatures) are typically 19 s rising

temperature and 14 s falling temperature

Time constant:

None

Resistance range at 25 °C [77 °F]

2.5 kOhm at 20 °C [68 °F] ±5 %

ES110 Series Inlet Air Temperature

Sensor Probes

The ES110 probe is a thermistor mounted into a plastic lead frame and

assembled into a metal body. This subassembly is then overmolded to

produce both the electrical connection system and the hexagonal shape

for easy installation. Two end configurations are available depending

upon response required or degree of protection. The all-plastic design

reduces heat loss through the sensor, thereby reducing wind chill effects.

Operating temperature range:

-40 °C to 155 °C [-40 °F to 311 °F]

Encapsulation:

Standard NTC (Negative Temperature Coefficient) epoxy

protection

Lead material:

Terminals are 2,8 mm x 0,8 mm [0.11 in x 0.03 in]

brass with a copper flash protection layer with final plating

to customer requirement (silver, tin, gold, etc.)

Dissipation constant:

0.85 mW/°C in still air at 25 °C [77 °F]

Time constant:

1 s in liquids, 12 s max. in still air

Resistance range at 25 °C [77 °F]

2.5 kOhm at 20 °C [68 °F] ±5 %

Temperature Sensor Probes are finished thermister assemblies complete

with thermister housing, extension leads and sometimes a connector. A

variety of customized packages are available.
