Clamp On Leadless Coin NTC Thermistors For Car Oil And Water
Transmission Temperature Measurement
Analog temperature sensor (NTC type) with recommended range of up
to +125°C. Example of use: oil temperature, transmission
temperature and water temperature.
- Temperature measurement and compensation
- Internal combustion locomotive
- large motor
- oil soaking transformer
- oil temperature, transmission temperature and water temperature.
This type of sensor is commonly used as oil temperature sensor (for
engine oil or transmission oil temperature measurements) and as
water temperature (for engine coolant temperature measurements)
- Front surfaces silver-plated
- For clamp contacting
- Alternative resistance ratings, rated temperatures, resistance
tolerances and disk geometries available on request.
- The nominal resistance value and B value error range are small,
the product consistency and interchangeability are good, which can
be supported by various domestic and imported car instruments.
1.Dimension
1.1,The thermistor base is a semiconductor made of manganese oxide,
cobalt oxide, nickel oxide and other materials sintered at high
temperature, and the surface of the resistor is infiltrated with
electronic silver paste as an electrode;
1.2,The surface is smooth, without deformation and defect; the
silver layer is bright, without flow marks or exposed bottom or
accumulation
2. The main parameters of the resistor meet the requirements in
Table 1 below
| Temperature(℃) | Resistance(Ω) | Allowable deviation(Ω) |
| *85±0.1 | 206 | ±22 |
| *110±0.1 | 96 | ±10 |
2.1 Dissipation coefficient:≥ 11mW/℃
2.2 Thermal time constant:≤ 60s
2.3 Max. Power: 220mW
2.4 Test power: ≤ 0.1mW
2.5 Operating temperature range:(-55~+125)℃
3.Reliability
3.1 High temperature storage: After the resistor is placed in an
electric heating oven at (150±5)℃ for 200 hours, the surface
electrode of the resistor has no yellowing or discoloration, and
the change rate of its zero-power resistance value is ≤ ±2.5%;
3.2 Temperature shock: resistance -40℃ 30min → +25℃ 5min → 150℃
30min → 25℃ 5min for 5 cycles, the change rate of zero-power
resistance value is ≤ ±2.5%;
3.3 Low-temperature storage: After the resistance is stored in a
low-temperature box at -40℃ for 200 hours, the electrode has no
yellowing or discoloration, and the change rate of its zero-power
resistance value is ≤ ±2.5%;
