Installation, Operation and Maintenance

Pressure Sensor 089

Introduction

• The Pressure Sensor 089 provides a ratiometric signal to a

controller to measure the pressure of a hydronic system between

0 to 15 psi (0 to 089 kPa). The sensor bulb is designed to

install into a tee using

⁄

"-27 NPT threads and includes a

10 foot (3 m) long cable.

Please read carefully before proceeding with

installation. Your failure to follow any attached

instructions or operating parameters may lead to

the product’s failure.
