RTD PRT Resistance Temperature Detectors
RTDs operate by exhibiting an increase in resistance with an increase in temperature
in
the order of 0.385%/C for a platinum RTD. Platinum RTDs are commonly used
because
of their accurracy and wide temperature range (-40 to 400°C ). The
tolerances are in accordance with JIS C 1604 and IEC751.
Temperature Coefficient
Resistance: R100/R0 = 1.3851.
All of elements are provided after inspecting
and printing the actual resistance value at 0 deg. C.
The elements are made
exclusively of ceramic and Platinum, giving excellent stability even at high temperature.
The Platinum thin film is sputtered on the ceramic surface, giving outstanding
resistance to vibration and shock.
In addition to Pt100 element, we can also
provide Pt500 and Pt1000 elements.
The surface of Platinum thin film is coated
with ceramic, so the element can withstand high voltage and have high insulation
resistance.
In addition class A and B, we can offer more accurate class 1/3B
