_____________________________________________________INTRODUCTION

The HPT 100 is a series of pressure transmitters specifically designed to meet the ultra-clean and

ultra-high stability and reliability requirements of the semiconductor industry. Because most of

the process gases to be measured by the HPT 100 are highly reactive and pose toxic threats to the

facility personnel, the manufacturing tolerances and operating specifications are very strict.

Many of these units will be permanently welded into the gas distribution system, so the design

includes external access to the electronic circuitry by qualified repair personnel and zero and

span pots for field calibration.

All HPT 100 units are labeled with the C.E. mark certifying compliance with European standards

for RFI/EMI immunity.

HPT 100 units with the suffix ‘1’ in the model number are labeled with agency approval from

Canadian Standards Association (CSA) and Laboratoire Central Des Industries Electriques

(LCIE) for Intrinsically Safe and Non-Incendive Systems for operation in hazardous locations.

HPT 100 units with the suffix ‘2’ in the model number are labeled with CSA approval for

operation in Division 2 Locations.

HPT 100 units with the electrical connection suffix “N” or “C” or “P” are rated NEMA 4X

Enclosure by CSA and IP56 Enclosure by LCIE. Electrical Connection Suffix “N” or “C” is

recommended for outdoor use.
