SFK02+ UNI Modbus

Immersion sensor with Modbus RS485 interface for temperature measurement of gases and liquids in HVAC applications. The sensor can be optionally screwed directly into a bonded pocket (see accessories). Types SFKH02+ with a 70 mm neck pipe are designed for applications with insulation materials. The measuring insert can be exchanged without disassembling the entire sensor. A hinged cover and tool-free wiring as well as removable cable entries ensure a quick and easy installation.
