Ultra Precise RTD Sensors for Industrial Applications P-L-A-6-20-0-PS-15 P-L-A-6-20-0-PS-15
  • 100 Ohm DIN Platinum RTDs with Class “A”, 1/3 DIN and 1/10 DIN Accuracies
  • Temperature Range Varies with Cable Selection and Accuracy Class (See Description Below).
  • Available in Two Models:
    Standard Closed End Sensor for Immersion Applcations
    Air/Gas Measurement Sensors with Open Ends and Vent Holes.
  • Probes Available in 6mm, 3mm, 1/8" and 1/4" Diameters.
  • 4-Wire Construction in 6 and 3 mm (1/4 and 1/8") Diameters
  • Both Models are Available As Straight Sheaths or With The Followng Mounting Threads: 1/8, 1/4, 3/8 and 1/2NPT, and 6mm, 8mm and 10mm Sizes

Omega's line of Ultra-Precise RTD temperature sensors provide customers with a product that offers sensor accuracies that are far tighter than are available in most standard RTD sensors on the market today. These sensors are manufactured using DIN Platinum RTD elements (temperature coefficient = .00385 ohm/ohm/°C) with Class A, Class 1/3DIN or Class 1/10DIN accuracies. This makes Omega's Ultra-Precise RTDs among the most accurate industrial temperature sensors available.

These sensors are available in two styles:
Type P-M style closed ended immersion sensors for use where the sensors will be immersed in a fluid.
Type P-L style exposed element sensors for use in direct contact with air or gasses for more accurate measurement of these substances.

There are four probe diameters available including 3mm, 6mm, 1/8" and 1/4", with lengths starting at 50mm (2") with a number of standard lengths available (see ordering table below). A variety of mounting threads are available including: 6x1mm, 8x1mm, 10x1mm, 1/8NPT, 1/4NPT, 3/8NPT and 1/2NPT (Note: 6mm mounting threads are not available on 6mm diameter probes).
Please note that 1/8" and 3mm diameter probes without threaded fittings and with "-P", "-PS", "-TS", "-GS" and "-S" cables include a transition fitting at the end of the sheath to accommodate the cable diameter. If a transition fitting is not acceptable, then a type "-T" or "-G" cable must be specified.

Please note that the minimum recommended length for 1/10DIN accuracy probes is 6” for 1/4" (150mm for 6mm) diameter probes, and 4” for 1/8” (100mm for 3mm) diameter probes. This is due to the fact that in order to achieve these accuracies all stem conduction effects in the sensor must be eliminated. Also, please note that in order to lab certify 1/10DIN accuracy RTDs, it may be necessary for the probes to be longer than these lengths depending on the test equipment used to perform the certification. Omega can make these products shorter than the recommended lengths, but we cannot guarantee their performance. For 1/3DIN probes, a minimum length of 4.75" applies for 1/4" (120mm for 6mm) probes and 2.38" for 1/8" (60mm for 3mm) diameter probes.

The ultimate temperature range of the sensor is dependent upon both the element accuracy and cable selection as shown below (the tightest temperature range applies):

Temperature Range Examples:

P-M-A-1/8-6-0-T-3 has a Class A Element = -100 to 450°C, and "T" (PFA) Cable = -100 to 250°C, resulting in a sensor temperature range of -100 TO 250°C.

P-M-1/10-1/4-9-1/2-P-3 has a 1/10DIN Element = 0 to 100°C, and a P (PVC) Cable = -29 to 100°C, resulting in a sensor temperature range of 0 to 100°C.
