The industries we serve
Frequently asked questions
Answers to the most common questions about our products and services
No. Sensor and controller share one stainless-steel housing. An optional USB converter and sensorTOOL provide extended configuration.
No. Its stated measurement range is −40 to +1100°C, while the factory preset is 0 to +600°C. Configure it for the application.
The page specifies up to 80°C without cooling. This is an instrument ambient limit, separate from target-temperature range.
Yes. It specifies parallel analog/digital operation and a 200 mA open-collector output. Match wiring and output configuration to the control system.
It provides an alignment aid and red/green status LEDs for alarms or system state. Advanced settings use the optional USB converter and sensorTOOL.
