DESCRIPTION
Ni1000SOT is a nickel thin film resistance temperature detector (RTD) that is suitable for use in contact
temperature sensing.
The devices are manufactured by PVD-deposition on a silicon substrate. The thin film structure is covered by a
passivation layer for environmental protection and enhanced stability. The nickel elements are mounted on lead
frames and encapsulated in SOT23 packages. This technology allows the production of miniature, low cost, high
precision temperature sensors.
The characteristics of the temperature sensor comply with the former DIN 43760 standard. It is qualified for the
most demanding automotive applications (incl. exposure to hot oil) and is suitable for many more applications in
harsh environments.

SELF HEATING EFFECT
For accurate temperature measurement it is recommended to choose a small current to avoid self heating of the
nickel sensing element. The temperature error caused by excessive measurement current can be calculated
using: T = P/EK
where P = I2 ∙R is the power generated by the measurement current and EK is the self heating coefficient.

ELECTRICAL CHARACTERISTIC
The characteristic of the nickel temperature sensor is specified as per DIN 43760. The large Temperature
Coefficient of Resistance (TCR) of the Ni-RTD, 6178 ppm/K, offers greater sensitivity than other types of RTD’s.
The electrical characteristic can be described by the following equation:
R(T) = R0 (1+aT+bT2+cT4+dT6)
Coefficients: a = 5.485 x 10-3
b = 6.650 x 10-6
c = 2.805 x 10-11
d = -2.000 x 10-17
T(R) = a´+b´(1+c´R)½ +d´R5+e´R7 dT < 0.12 K (higher order equations on request)
Coefficients: a´= - 412.6
b´= 140.41
c´= 0.00764
d´= - 6.25 x 10-17
e´= -1.25 x 10-24
Tolerances: Class B (0.4+0.007 x |T|) in range from 0oC to +160 °C
(0.4+0.028 x |T|) in range from -55oC to 0 °C

Analogue Interface Circuit for high accuracy measurement
The following circuitry utilizes the output of a bridge circuitry which is amplified in order to improve the
measurement resolution. By bridging RNI with an optional 3.65kOhm resistor this circuitry can be linearized.
Example of analog interface circuit for high accuracy measurement using Ni1000SOT sensor
The output voltage will be calculated by the following equation:
UNI = RNI/(R1+RNI)∙VCC∙[1+R4∙(1/R2+1/R3)]–R4/R2∙VCC
