Four Channel Temperature Alarm Docs
The temperature in a pipe is monitored with four RTD Pt-100 Sensors, The
type of probe could be Extruder RTD probes with Bayonet or Compression
Fitting, Get it from Omega. To keep costs low you can choose small thin
film RTD sensors, they will be fast but on rough usage may break.
The time taken to measure the temperature at the 4 points will be less
than 4 seconds. An optional display of the measured temperature as shown
above can be avoided by using a DMM to adjust the setpoint.
The Analog Timer Module can be set from 0- 30 minutes. If out-a remains
high even after set time a out-b alarm goes on to sound a buzzer and
flash a LED light.
