Products Description


input signal
Thermal resistance(RTD): Pt100,Pt1000,Cu50
Thermocouple(TC):K,S,R,B,N,E,J,T
Temperature range
-270~+1820℃(set according to sensor measurement capability)
Conversion accuracy
≤0.2% or 0.2K
Output signal
4-20 mA(two-wire),HART
Alarm
When the sensor fails (open circuit or short circuit), the output drops to ≤3.6mA or the output rises to ≥21.5mA
Maximum load (Note 1)
(V power- 9 V)/0.025A (output current)
Limit current
≤25mA
Power supply voltage (Note 2)
9...30VDC
Response time
1S
Lightning protection (Note 3)
±4000V(≤5 times)
Anti-pulse group(Note 4)
±4000V
Anti-radio frequency interference
>10V/m(80MHz~1000MHz)
Ambient temperature
-40~85℃
Temperature drift
0.008%FS/1℃
Long-term stability
≤0.1℃/year or 0.05%/year


Note:
1: With HART protocol, the maximum load is: (V power- 12 V)/0.025A (output current). When the rail is installed, the maximum load
is: (V power- 10 V)/0.025A (output current).
2 : With HART protocol, the power supply is 12 ...30VDC. When the rail is installed, the power supply is 10 ...30VDC.
3 : With HART protocol, no lightning protection.
4 : With HART protocol or rail installation, anti-pulse group: ±3 000V.

Note：
1 : When selecting multiple input signals (ie universal input), it is recommended to equip a PC programmer for range setting.
2 : HART protocol only applies to top-mounted products.
3 : The range needs to confirm the specific temperature range so that it can be set at the factory.
