FOXBORO H90TTYD024Y0 may be a temperature transmitter. The following are the general parameter information of a temperature transmitter:
- Input signal type: It may use thermocouples and thermal resistors as temperature measuring elements, such as common K, E, S, B, T, J type thermocouples, or PT100, CU50 thermal resistors.
- Measurement range: For thermocouple temperature transmitters, different thermocouple types have different measurement ranges. For example, type K thermocouples can generally measure from 0 to 1300 °C; for thermal resistance temperature transmitters, PT100 can generally measure from -200 to 850 °C.
- Output signal: It is usually a 4-20mA DC signal linearly related to the temperature. There may also be 0-5V, 0-10V voltage signals or RS485 digital signal outputs.
- Accuracy grade: The general accuracy grades of temperature transmitters are ±0.1%, ±0.2%, ±0.5%, etc. The specific accuracy needs to be determined according to the actual situation of the product. For example, the maximum error of some thermocouple transmitters of FOXBORO is approximately ±0.25% of the span.
- Operating ambient temperature: Generally, it is from -20 to +70 °C, but it may vary for different products.
