THIN FILM RTD ELEMENT

INTRODUCTION 

CRZ series thin film elements are highly stable resistance temperature detectors suitable for temperature range of -40 to +400°C. CRZ elements are produced by state-of-the-art technology using processes like thin film laying by sputtering, ultra fine patterning by photolithography and dry etching, resistance value adjustment by digital laser trimming.  After trimming, the element surface is coated with ceramic, so the elements can withstand high voltage and have high insulation resistance

FEATURES

  1. Excellent long term temperature stability.
  2. Outstanding resistance to vibration and shock.
  3. Temperature resistance and characteristics conforming to IEC, DIN and/or JIS.
  4. Each CRZ element is individually tested for actual resistance value at 0°C and batched together in sealed plastic pouches with inspection results printed on the pouch.

STABILITY CRZ elements possess excellent long-term stability. After continuous heating of model CRZ-1632 at 400°C for for 1,000 hours the margin or error at 0°C is within 0.008 W (0.02°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% value of the  temperature change and the associated 90% response time is T2-T1.
