Relay Unit for Thermometer with Electric Contacts, high or low threshold
KR-A2
Calibration : Not available
JCSS Accredited Calibration : Not available
A relay unit to control the temperature to the fixed temperature range, attached with the thermometer with one or two electric contacts
Feature
This is a relay unit to control the temperature to the fixed temperature range, used with a thermometer with one or two electric contacts.
The current flowing into circuits of the relay unit (delay circuit and self-hold circuit) becomes weak before it flows into contact section so that it prevents sparks and adhesion of contacts. Also, the delay circuit prevents the contacts from chattering when they open even if a slight vibration is given to the contacts.
