CRZ Pt100 薄膜鉑熱 感溫電阻無鉛

Thermometer

　


Description

CRZ Platinum Thin Film Resistance Thermometer Elements are the epochmaking temperature detectors developed by making full use of the state-of theart high technologies such as thin film laying by sputtering, ultra fine patterning technology by photolithography and dry-etching method, resistance value adjustment by digital trimming for accurate resistance by Hayashi Denko.
1. The tolerances are in accordance with JIS C 1604 and IEC751.
2. Temperature Coefficient Resistance: R100/R0 = 1.3851.
3. All of elements are provided after inspecting and printing the actual resistance value at 0 deg. C.
4. The elements are made exclusively of ceramic and Platinum, giving excellent stability even at high temperature.
5. The Platinum thin film is sputtered on the cermic surface, giving outstanding resistance to vibration and shock. 
6. In addition to Pt100 element, we can produce Pt500 and Pt1000 elements.
7. The surface of Platinum thin film is coated with ceramic, so the element can withstand high voltage and show high insulation resistance. 
8. In addition classA and B, we can offer more accurate class1/3B, of our own.

TOLERANCE

　


STABILITY

After continuously heating the CRZ-1632 at 400 deg. C for 1000 hours, the
margin of error at 0 deg. C is within 0.008 ohm(0.02 deg. C).

　


SELF-HEATING

A current passing through the resistance element causes the element to heat.
So the current used with the element should not exceed 1mA.
