Fiber optic temperature sensor TEMP 2S

wall-mountDIN railstrap-on

Overview
The TEMP2S is a ready-to-use connected temperature sensor equipped with two remote contact probes. It is designed to monitor internal and external temperatures in storage rooms, cold rooms and other environments that require long-term, reliable measurements.

Key functions

• Simultaneous temperature measurement at two locations via two remote probes
• Periodic transmission of temperature data, with optional local logging
• Event-triggered transmission when configured thresholds are exceeded (high and/or low)
• Local and remote configuration of periodicity, transmission modes and alarm thresholds
• Data logging to optimize device autonomy
• Configurable redundancy with a set number of repeats per frame
• Configurable alarm repetition for persistent events
• Alerts for product errors, configuration issues and low battery

Highlights

• Two remote probes (contact type)
• Autonomy examples up to >15 years depending on version and configuration
• Periodic and/or event-triggered transmission modes
• Local configuration via USB-C and remote configuration via network
• Data logging capability
• Available wireless variants: LoRaWAN (EU863-870, US902-928, AU915-928, AS923-1) and Sigfox (RC1, RC2, RC4)
• Also available in a variant with one ambient probe + one external probe

What the sensor does

• Measure temperatures periodically and record values locally if configured
• Detect temperature deviations and losses
• Trigger alarms when configurable thresholds are exceeded (high and/or low)

Configuration and connectivity

• Local configuration via USB-C port
• Remote configuration over the network to set periodicity, transmission modes and alarm thresholds
• LoRaWAN Class C support when using an external power supply
• Configurable lifetime frame and transmission repetition settings

Decoding / Integration
Device payload can be decoded using the manufacturer's codec solution for integration into back-end systems or IoT platforms.
