Sensors Can be Installed Using
OMEGABOND® 101 and 200 Epoxies |
|
|
Models SRTD-1 and SRTD-2 are polyimide insulated surface mount RTD
temperature sensors designed to provide a practical method for measuring
surface temperatures. These sensors are small and flexible, and their
low mass has minimal thermal effect on the material being measured.
They are ideally suited for applications where the sensor can be mounted
to the surface being measured using adhesives (OMEGABOND® 101 and
200 epoxies can be used) or other mechanical mounting methods.
Specifications
Usable Temperature Range: -200°C (-320°F) to 260°C (500°F) continuous, 290°C (550°F)
short term
Sensing Element: 100 ohm platinum, alpha = 0.00385 ohm/ohm/°C
Accuracy (Tolerance): see accuracy table below
Stability: <0.2°C drift per year at rated service temperature
with proper mounting
Response Time: 70 msec to reach 63.2% of a step change in temperature
in water flowing at 3 ft/sec transverse to the sensor
Self-Heating Effect: Bare sensor will rise less than 1°C while
dissipating 3 milliwatts in still air
Insulation Resistance: 50 megohms minimum @ 50 Vdc (dry conditions at room temperature)
Thickness: Very thin polyimide-insulated, wire-wound sensor is 0.64 mm (0.025") thick over the sensor and 1.53 mm (0.060") thick over the cable (max)
Lead Wire:1 m (40") long 3-conductor, #26 AWG stranded nickel-plated copper, PFA insulated ribbon cable (standard)
Minimum Bend Radius for Mounting: 3/8" transverse to element, 1-1/2" longitudinal to winding
