Temperature sensors SensyTemp TSP111, TSP121, TSP131

The ABB SensyTemp TSP111 is a versatile temperature sensor designed for standard applications like pipes and tanks, particularly for low to medium process requirements. It is a model without a thermowell, intended for insertion into an existing one, and can accommodate different sensor types like RTDs or thermocouples. Communication options include 4–20 mA, FOUNDATION Fieldbus, PROFIBUS PA, and HART. 
Key features and specifications

• Sensor types: Compatible with various RTDs or thermocouples (e.g., Pt100 RTDs or K, N, J, E, L, S thermocouples), SensyTemps can measure a wide range of temperatures.
• Design: It is an insertion-type sensor designed to be used with an existing thermowell. This allows for replacement during operation.
• Communication: Supports multiple communication protocols for data transmission, including 4–20 mA, FOUNDATION Fieldbus, PROFIBUS PA, and HART.
• Application: Suitable for standard industrial applications such as pipe and tank engineering, especially where low to medium process requirements are met.
• Performance: Offers a short response time and high vibration resistance, making it suitable for demanding processes.
• Materials: Available with different sensor and material options, such as stainless steel or Inconel, for various applications. 

• The sensor is inserted into an existing thermowell, which protects it from the process medium.
• The sensor measures the temperature of the medium and converts it into an electrical signal.
• This signal is then transmitted to a controller or monitoring system using one of the supported communication protocols, which can be interpreted as a temperature reading.
