thermal resistance with threaded connector
http://www.ahdqjt.com time: 10/22/10 09:55application:
it is usually connected with display meter, recording meters and computer, etc. to directly measure temperature of liquid, vapor, gas and solid surface ranging from -200 to 500 during various production processes.
operation theory:
it is based on that temperature change results in change of its resistance. when the resistance value changes, the working instrument will display relevant temperature.
features:
- spring thermal sensor with good shock-proof performance
- no compensational wire, spare cost
- high measuring accuracy
- high mechanical strength, good pressure-resistant performance
- imported film resistor with stable & electric performance
executive standard:
iec751
jb/t8622-1997
jb/t8623-1997
measuring range & tolerance:
insulation resistance at normal temperature
the insulation resistance between electrode and protection tube of armored resistance shall be no less than 100m under condition that environment temperature is 15-35, relative humidity is no more than 80%, and testing voltage is d.c.10-100v
remarks: t is absolute value actually tested with thermal sensor.
