Platinum Resistance Temperature Detector

L 420

L series PRTDs are designed for large volume applications where long term stability, interchangeability and accuracy over

a large temperature range are vital. Typical applications are Automotive, White goods, HVAC, Energy management,

Medical and Industrial equipment.
