850 Series Electronic Indicating Temperature Transmitter/Switch
850 Series Electronic Indicating Temperature Transmitter/Switch
Key Features
- Utilizes PT100 technology to provide continuous temperature monitoring,
electronic temperature switching, and transmission of analog output of 4 mA to 20 mA
while providing local digital indication - Allows for one or two switching outputs as well as an optional analog output
- Two buttons on top allow simple adjustment of the temperature set points, reset points,
switching functions and the measuring range of the optional analog output - Wide measuring range (between -300 °F and 1,100 °F / -200 °C and 600 °C) covers
the majority of temperature measuring and switching applications - 1/2" NPT male standard connection, 1/4" NPT optional
- A variety of stem lengths are available for maximum versatility (also available with
adjustable insertion lengths) - A version with tapered stem is also available for rapid response times
- Durable stainless steel housing and wetted parts
- The housing and replaceable measuring insert are screwed together to allow
the exchange of the measuring insert without opening the connection to the process
Application:
- Mechanical engineering
- Heating and cooling circuits
- Air conditioning technology
- Plant construction
- Environmental technology
