PLATINUM THIN FILM RTD ELEMENT

INTRODUCTION:

The epoch-making CRZ Platinum Thin Fild RTD elements have been successfully developed by making full use of the state-of-the-art high technologies such as the sputtering technology laying think films, the ultra fine patterning photography and dry-etching methiods, and the resistance value adjustment by digital trimming for the accurate resistance.
Our automated manufacturing process at each stage enables to offer our products being at reasonable prices as well as meeting IEC and JIS Standards.

FEATURES:

The elements are RoHS compliant products.
The tolerances comply with JIS C 1604 and IEC751.
Temperature Coefficient Resistance: R100/R0 = 1.3851.
The mass production system achieved low price elements.
In addition to Pt100 element, we can produce Pt500 and Pt1000 elements.
The stability is excellent even at high temperature due to the construction.
All of elements are provided after inspected and printed the actual resistance value at 0 ℃. You can recognize that at a glance.
Outstanding vibration and shock resistibility is improved comparing with wire wound types by circuit-sputter technology.
The surface of Platinum thin film is coated with ceramic, so the element can withstand high voltage and show high insulation resistance.
In addition classA and B, we can offer more accurate class1/3B, and lower cost class 2B.

STABILITY: After continuously heating of model CRZ-1632 at 400°C for 300 hours, the drift at 0°C is within 0.06 W (0.15°C)
RESPONSE TIME DATA: Response time is the time required for the element to indicate the stated percent (%) value of the temperature source. The following table indicates response characteristics of the temperature change from T1 to T2. T3 is 90% change of that temperature change and the associated 90% response time is T2-T1.
Model	Response Time (Time constant: 63.2%)/sec)
	Still Air	Still Water
CRZ-1632	4.3	0.3
CRZ-2005	4.8	0.4

ELEMENT DIMENSIONS

Model	Element dimension (mm)	Lead dimension (mm)
CRZ-1632	3.2 x 1.6 x 1	0.25 (W) x 0.15 (H) x 12mm long Gold plated Nickel leads
CRZ-2005	2.0 x 5.0 x 1	0.25 (W) x 0.15 (H) x 12mm long Gold plated Nickel leads

SELF-HEATING AND MEASURING CURRENT
A current used with an element should not exceed the specified current. When a CRZ-1632 is loaded in a 8.0 mm hollow protection tube, its resistance rises only 0.02W(approx.0.05°C ) at 1mA when measured in agaitated water at 0°C. But the resistance value rises to 0.86W(approx.2.2°C) at 5mA.
