功能特点PK系列温度在-200到+800°C之间标准标称值和公差作为单或双温度传感器扩展温度测量范围耐高温抗冲击优异的温度波动稳定性JUMO介绍:德国JUMOGmbH&KG公司成立于1948年,位于德国中部城市Fulda
Standard | EN 60 751 |
Temperature coefficient | α = 3.850 x 10-3°C-1 (between 0 and 100°C) |
Temperature range | -200 to +600°C |
Tolerance | Temperature validity range Class 1/3 DIN B: - 70 to +250°C Temperature validity range Class A: -200 to +600°C Temperature validity range Class B: -200 to +600°C |
Measuring current | recommended: 1.0mA |
Maximum current | 20mA |
Operating conditions | Platinum-ceramic temperature sensors may not be used unprotected in humid ambient conditions (condensation) or corrosive atmospheres. Because of their special internal construction, the temperature sensors only have a limited resistance to shock and vibration. However, they exhibit excellent temperature stability and are free from hysteresis. The user may have to carry out some checks before operation. |
Connecting wires | The connecting wires are made of a palladium-gold alloy, 0.27mm thick. On the versions H 2 x Pt100, the connecting wires of the first measurement winding are longer (L1 +1mm), to mark the individual winding more clearly. Any unnecessary bending of the connecting wires must be avoided, as this may result in material fatigue and a wire break. |
Measurement point | The nominal value specified refers to the standard connecting wire length L1. The measurement is acquired 2mm from the open end of the wire. If the wire length is altered, changes in resistance will occur, which may result in the tolerance class not being met. |
Long-term stability | max. R0 drift 0.03%/year (see Data Sheet 90.6000 for definitions) |
Insulation resistance | >10MΩ at room temperature |
Vibration strength | see EN 60 751, Section 4.4.2 |
Shock resistance | see EN 60 751, Section 4.4.1 |
Self-heating | Δt = I 2 x R x E (see Data Sheet 90.6000 for definitions) |
Packaging | Blister pack |
Storage | In the standard packaging, JUMO temperature sensors, PK/H style, can be stored for at least 12 months under normal ambient conditions. It is not permissible to store the sensors in aggressive atmospheres, corrosive media, or in high humidity. |
