Safety Instructions
1. Prior to installation or removal:
• Depressurize and vent system
• Drain below sensor level
2. Confi rm chemical compatibility before use.
3. Do not exceed maximum temperature/pressure specifi cations.
4. Wear safety goggles or faceshield during installation/service.
5. Do not alter product construction.
6. Dispose of properly; DO NOT INCINERATE!
USE THE ATTACHED ADHESIVE LABEL TO PRESERVE THE SAFETY INSTRUCTIONS!
1. Description
The 2450 Pressure Sensor has a one-piece injection molded PVDF body and ceramic diaphragm for superior compatibility in corrosive
liquids. These sensors are available with Digital (S
ranges for optimal measurement resolution. Built-in temperature compensation provides outstanding accuracy over a wide operating
range. Versions with / in. union process connection are best suited for in-line installations.
