Dynisco APT3291-50 Transducer

DYNISCO MODEL PT291 Flange Mounting Button-Seal Pressure Transmitters for Process Control in Hazardous Areas
Description The PT291 transmitters were designed for applications where an adjustable flange configuration is required. Models are available with Factory
Mutual (FM) explosion - proof or FM intrinsically safe (SIRA) approvals. Both models are approved for Class I, Division I, Groups A, B, C and D. The
290 Series is the ideal choice for low pressure applications.
