GENERAL FEATURES
Model 130 has a female nut for the process connection.
It is suitable for use in applications that do not require sealing.
In order to move the connection head away from the hot area, a cooling neck has been added between the head and the process connection fitting. The connecting nut is movable on L2. Nut thread size must be stated when ordering.
In standard production, outer protective SS316 stainless steel is used. Different material requests should be notified.
The sensor can be manufactured as T/C or RTD. For detailed information, see the Sensor Type page.
The sensor can be manufactured in Mineral Insulated or Conventional structure (by passing insulation ceramics on T/C wires or RTD extension wires). For detailed explanation, see the Sensor Structure page. The sensor can be produced in Integrated or Inset structure. For a more detailed explanation, see the General Structure page.
Various options can be found on the Connection Head Types page.
SENSOR TYPE:
T/C - Thermocouple - Thermocouple T,J,E,N,K,S,R,B
What is T/C?
Thermocouple is a temperature measurement element formed by pairing two different metal wires. Two different metal wires are welded at one end to form a pair.
If the hot junction is exposed to heat, an electrical potential difference of the order of mV occurs between the welding point and the open ends of the wires.
Simply put, the reason for this potential difference is the tendency of free electrons in the atoms of both wires to escape from the hot region to the cold region.
Since the two wire materials are different, they contain different numbers of free electrons. Therefore, for example; At a given temperature, 1 electron from the positive leg will move to the cold region, while 2 electrons will move from the negative leg.
The value measured between the cold ends of the wires will be the value given by 2-1 = 1 electron.
When the given temperature is doubled, the flow of 2 electrons from one leg and 4 from the other leg naturally results in a value equivalent to 2 electrons on the measuring instrument.
is read.
Wires must be insulated from each other to avoid creating a short circuit anywhere other than the welding point. They are also placed in an outer sheath to protect them from contamination in environmental conditions.
In some applications where temperature changes must be detected very quickly, even if the hot junction of the wires is left unprotected and exposed, the long-term stability of such T/Cs without external protection will be unreliable.
Namely; For example, if a T/C whose first leg is made of pure Platinum (Pt) and the other leg is an alloy of Platinum and Rhodium (PtRh10%) is left unprotected at a temperature of approximately 1,000°C, the gases in the furnace will penetrate the wires. These gases contain carbon as well as atoms broken off from the metals used in the internal structure of the oven (such as the oven construction, conveyors, transport carts and sometimes the material itself). T/C wires interacting from this common dirt become identified with each other.
Choosing a thicker wire diameter is a factor that extends the life of the sensor.
It is very important that the T/C signal is transmitted with the appropriate compensation cable. For example, a "K" type sensor signal can only be carried with a "K" type cable. Otherwise, unpredictable measurement errors will occur.
SENSOR TYPE:
RTD - Resistance Temperature Detector - Resistance Thermometer Pt-100, Pt-500, Pt-1000
What is RTD?
Resistance thermometer; It is a type of temperature sensor whose resistance increases in response to increasing temperature. The material they are made of and the products they produce at 0°C
They are named with the resistance value in units.
For example; Pt-100 (which is the most commonly used variety) indicates a sensor made of Platinum material and having a resistance of 100 at 0°C. Although there are models that can operate between -200...+1000°C, their use is generally preferred at lower temperatures.
CI.C +/- [0.60+ (0.010 x t)] °C +/- 1.60 °C @ 100°C
CI.B +/- [0.30 + (0.005 x t)] °C +/- 0.80 °C @ 100°C
CI.A +/- [0.15+(0.002 x t)] °C +/- 0.35 °C @ 100°C
CI.1/3 DIN +/- [0.10+(0.0017 xt)] °C +/- 0.27 °C @ 100°C
CL. 1/10 DIN +/- [0.03+(0.0005 x t)] °C +/- 0.08 °C @ 100°C
Unless stated otherwise, SIRIUS SENSOR produces with DIN EN60751 - CI.B as standard.
As with T/Cs, the RTD signal must be transmitted via the appropriate cable. They can also be produced for 2-wire, 3-wire or 4-wire connection. Unless stated otherwise, SIRIUS SENSOR produces 3-wire as standard.
2-wire connection should not be preferred as the resistivity of the connection cables will be added to the measurement.
In 3- and 4-wire connections, the Wheatstone bridge inside the measuring device prevents line resistance from affecting the measurement.
