For precise temperature measurement the Platinum Re- sistance Thermometer offers the best overall advantages in repeatability and stability over a long period. High accuracy allows replacement of a sensor without any need for re-adjust of the connected measuring devices or thermostats. Platinum resistance temperature sensor on ceramic substrate intended for installation into any housing depending to user’s re- quirements. Very small and quick sensor, only suitable for further treatment. Notice: do not cut the sensor leads. Thermal response time refer to manufacturer data: T 0,9 in the air 10 s, in water <1 s. Part number: 019061 Platinum resistance temperature sensor on ceramic substrate pro- tected by a heat-shrinkable sleeve and with PTFE isolated stranded wire. The TF101K version can be installed in motor or transformer windings. When build-in into windings do not pressure the sensor element. Precautions should be taken to protect sen- sor and extension leads against push and pull forces. Thermal response time T 0,9 in the air 100 s, in water 19 s. With 2-wire connection and cable-length of 2 m there is a temperature-failure of approx. 0.51 Ω = 1.32 K caused by the line resistance. Cable length: 2000 mm Weight: 10 g Part numbers: T223154 2-wire T223134 3-wire Sensors TF101U2 are encapsula- ted in a stainless-steel-shell V4A. They are suitable for measuring temperatures in fluids, at surfaces or for inside or outside applicati- ons. The protection class is IP 66. The version with PVC-insulated cable (3 x 0,25 mm 2 in one cable) can be easily wired. The maximum ambient temperature is 105 °C. The sensor with cable 30mm (PVC) can be mounted in ter- minals in switchgear cabinets to measure temperature in en- closure. The version with PTFE-insulation (3 x 0,14 mm 2 single wires) with- stands peak-temperatures up to 200 °C Weights: PVC: 2 m = 50 g, 10 m = 250 g, 30 mm = 15 g PTFE: 2 m = 20 g Part numbers: T223051 3-wire 2 m PVC -30...+105 °C T223058 3-wire 10 m PVC -30...+105 °C T223052 3-wire 2 m PTFE -50...+170 °C T223047 2-wire 30 mm PVC -30... +80 °C2018-01-17 rot rot weiß Ø 4,5 2000 ±10 10 TF101N -70°C...+500°C TF101K -50°C...+170°C TF101U2 -30°C...+105°C -50°C...+170°C -30°C...+80°C

The resistance must be compensated. The resistance of a connecting cable can be calculated as follows: R [Ω] = 2 x l/(k x A), l = cable length [m], k = conductivity [S x m/mm 2] e.g. Cu = 56, A = cross sectional area [mm2] For example copper-wire: I = 50 m, cross sectional area 1 mm2: R = 2 x 50/(56 x 1) = 1,79 Ω, Resulting error = 1,79 Ω/0,385 Ω x K = 4,6 K. ZIEHL thermostats of TR series are generally insensitive to interference in the sensor line. Occasionally, however, undesirable switching is unavoidable, especially when temperature is near the switching point. For this reason it is highly recommended that cables are not laid parallel to power current lines over long distances. When appropriate, cables should be screened or twisted together. 2-wire technique With 2-wire connection the line resistance is compensated for by a potentiometer in the thermostat, by programming (e.g. TR122D, TR600) or via wiring an external resistor. The advantage of the possibly simpler and more economical running of just two wires is counter- acted by the disadvantage of the manual compensation required in the case of longer wiring. Differences in resistance caused by temperature changes cannot be compensated. 3-wire technique With 3-wire connection, a third wire (sense) connected to the sensor registers the drop in voltage in one line. For compensation of line resistance it is assumed that the voltage drop in the second line is identical (i.e. the same wire and same wire temperature). Compen - sation is then performed automatically. Possible changes of resistance in the line due to temperature changes are also compensated for. 4-wire technique With 4-wire connection, impressed current flows via two wires to the sensor. Via a two sensor line the drop in voltage is measured directly at the sensor. Possible differences in the sensor connection wiring can be disregarded. A disadvantage is the higher costs involved in running 4 wires. Kombination of 2- and 3-wire technique When connecting 2-wire-sensors to units with 3-wire input, the line resistance can be compensated by connecting a compensation resistor (Rk) between ground and sense- input. Rk must have the same value as the resistance of the line. The sensor then has to be connected to the + and the sense- input. Rk must be lower than the permitted resistance for 1 line of the 3-wire-input. Units requiring 3-wire configurations can also be operated by 2-wire sensors. The sensor input is simply shortened. The line resistance need not be compensated. 3-wire sensors can be used as 2-wire sensors, simply by omitting one wire. 2-wire sensors can be branched at any desired position in a 3 or 4-wire connection system. In this case though, the line resistance of the two wires from the branching point to the sensor is not compensated. ZIEHL thermostats, series TR are designed for use with 2 or 3-wire connection.
