HK Instruments PTE-O Series Installation Instructions

INTRODUCTION
Thank you for choosing an HK Instruments PTE-O/OI series passive
temperature sensor. The PTE-O/OI series is intended for use in com-
mercial environments in HVAC/R applications.
PTE-O is used to sense outside air temperature. The temperature
sensor is housed inside a stainless steel sleeve that protects it from
the environment and condensation, ensuring long service life.
PTE-OI is used to sense outside air temperature and ambient lighting
conditions. In addition to the outside air temperature, the PTE-OI
includes an ambient illuminance sensor. The illuminance sensor is
hermetically sealed for protection.
The design approach has been to offer user-friendly and premium
quality products with economical pricing. PTE products are avail-
able with wide range of sensor types: NTC1.8k, NTC10k, NTC20k,
PT1000, Ni1000 and Ni1000-LG.
