Introduction

237484

Thank you for purchasing a Series PT-405 Explosion Proof Heavy Duty Pressure Transmitter from APG.
We appreciate your business! Please take a few minutes to familiarize yourself with your PT-405 and this
manual.

Series PT-405 pressure transmitters oer reliability over a wide range of pressures and in harsh industrial
conditions and hazardous locations. It is certied explosion proof for hazardous areas in the US and Canada
by CSA for Class 1, Division 1 environments and has a single seal for the highest safety factor. The integrated
electronics, wide operating temperature range, and durability, make the PT-405 the perfect instrument for
static and dynamic pressure measurements with an amplied output signal.

Reading your label

Every APG instrument comes with a label that includes the instrument’s model number, part number, serial
number, and a wiring pinout table. Please ensure that the part number and pinout table on your label

match your order. The following electrical ratings and approvals are also listed on the label. Please refer to

the Certicate of Compliance and Declaration of Conformity at the back of this manual for further details.
