ETC 32207771

Platinum Resistance Temperature Detector
LN 222
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.
