Structural Components	Temperature Sensing Element: PT100, PT1000, NTC 1K or NTC 10K depending on the selected version. Protective Probe Housing: Sealed cylindrical enclosure designed to protect the sensing element in livestock-house conditions. Signal Cable: Factory-connected cable transfers the resistance signal to the compatible climate controller or measuring device. Wire Configuration: PT100 and PT1000 versions can be supplied in different wiring arrangements; NTC versions normally use a two-wire connection. Connection End: Cable termination can be integrated into a compatible control panel, terminal box or farm climate controller according to project requirements. Optional Mounting Protection: Outdoor installations can be combined with an appropriate radiation shield where protection from solar radiation and weather exposure is required.
Working Principle / Structural Principle	PT100 and PT1000 are resistance temperature detectors. Their electrical resistance changes predictably with temperature. A PT100 element has a nominal resistance of approximately 100 ohms at 0°C, while a PT1000 element has a nominal resistance of approximately 1000 ohms at 0°C. The connected controller measures this resistance and converts it into a temperature value. In a two-wire RTD circuit, cable resistance forms part of the measured resistance and can affect measurement accuracy when cable runs become longer. Three-wire configurations provide compensation for cable resistance, while four-wire configurations provide higher measurement precision by separating the sensing-current and voltage-measurement circuits. NTC thermistors operate differently: their resistance decreases as temperature increases. NTC 1K and NTC 10K variants allow integration with controllers specifically designed for the corresponding resistance curve. After processing the sensor signal, the livestock climate controller can use the measured temperature as an input for automatic ventilation, heating, cooling or alarm functions.

Sensor quantity and installation-point planning for multi-house commercial farms. System matching designed according to local climate and farm conditions.
Installation & Maintenance	Install the sensor at a representative temperature-measurement point within the livestock house. In animal areas, the installation position should reflect the climate experienced by the animals rather than the temperature near the roof, heater or ventilation equipment. Avoid mounting the probe immediately beside heaters, cooling pads, air inlets, exhaust fans, doors or other locations where localized airflow or radiant heat could produce an unrepresentative reading. Outdoor sensors should be protected from direct solar radiation using a suitable radiation shield. Confirm the controller input type before wiring. PT100, PT1000 and NTC sensors use different resistance characteristics and must be connected only to compatible inputs. For longer RTD cable runs or projects requiring higher precision, three-wire or four-wire configurations should be considered where supported by the controller. Periodically inspect the probe, mounting point, cable and electrical terminals. Remove accumulated dust and farm residue without damaging the sealed housing or cable. During livestock-house washing, inspect cable routing and connectors before returning the climate-control system to normal operation.
Project Cases	Typical Commercial Pig House Climate Control Project: Temperature probes can be distributed through farrowing, nursery and finishing sections and connected to a centralized climate controller. The measured temperature provides a control reference for minimum ventilation, fan stages, air-inlet positioning, heating equipment and high/low temperature alarms. Multi-House Livestock Farm: PT100, PT1000 or NTC sensor types can be selected to match existing controllers when upgrading or expanding farm buildings, helping standardize replacement sensors while retaining compatibility with the installed control system. Outdoor Reference Measurement: A protected outdoor sensor can provide outside-air temperature information for climate-control strategies, seasonal ventilation settings and environmental monitoring. Project configuration should be determined according to local climate and controller functions.
Product FAQ	Q: What is the difference between PT100 and PT1000? A: Both are platinum resistance temperature detectors. PT100 has a nominal resistance of 100 ohms at 0°C, while PT1000 has a nominal resistance of 1000 ohms at 0°C. The correct type must match the input specification of the climate controller. Q: When should a three-wire or four-wire PT sensor be considered? A: These configurations help reduce measurement errors caused by cable resistance. They are useful where cable distances are longer or where higher measurement accuracy is required, provided that the connected controller supports the wiring method. Q: Can this sensor be used inside a pig house? A: Yes. The sensor is intended for demanding agricultural environments and is suitable for pig houses, poultry houses and other livestock buildings.
