Page 3: 1．Introduction
TY13－42A 3／18 1．INTRODUCTION The CL13 differential pressure switch is designed for detecting air filter pressure drop used in an air- conditioning system and warning for filter clogging, etc. Applications include clean room/bio clean room pressure monitoring. When using the CL13, read carefully this manual, which describes the operation procedure, and use the product correctly and effectively after understanding sufficiently the description. - Page 4 Rev.3 TY13－42A 4／18 (4) Precautions ①It is strictly prohibited to apply this differential pressure switch to life support systems or relevant equipment without our permission. ②This differential pressure switch is designed and manufactured to measure the difference of the pressure applied to the pressure lead-in unit. It is prohibited to use this differential pressure gauge for any other applications.

Page 5: 2．Applications
Be sure to turn off the power on both sides. 2．APPLICATIONS CL13 fine differential pressure switch will detect pressure difference between two selected locations (differential pressure), and close or open electric circuits as appropriate, or give an alarm. This switch is mainly used for detecting differential pressure associated with pressure loss in the air filter in air conditioning systems. -
