CHAPTER 1

INTRODUCTION

1.0 GENERAL

This chapter provides an introduction to the Model CYD211 Temperature
Monitor. The Model CYD211 was designed and manufactured in the United
States of America. A general description is provided in Paragraph 1.1,
specifications in Paragraph 1.2, safety summary in Paragraph 1.3, and
safety symbols in Paragraph 1.4.

1.1 DESCRIPTION

The Omega single-channel Model CYD211 Temperature Monitor provides
the accuracy, resolution, and interface features of a benchtop temperature
monitor in an easy to use, easily integrated, compact instrument. With
appropriate sensors, the Model CYD211 measures temperature from 1.4 to
800 K and in difficult sensing conditions, including high vacuum and
magnetic fields. Alarms, relays, user-configurable analog voltage or current
output, and a serial interface are standard features on the Model CYD211.
Backed by the Omega tradition of excellence in cryogenic and precision
temperature measurement for science and industry, the Model CYD211 is a
good choice for liquefied gas storage/monitoring, cryopump control, cryo-
cooler, and materials science applications, and for applications that require
greater accuracy than thermocouples allow.
