$
365
 Waterproof Case for 
Harsh Environments
 Compact Size
for Ease of Use
 Ideal for Freon and
Ammonia Applications
The PX177 uses silicon strain 
gages mounted on a beam that is 
coupled to a stainless steel diaphragm, 
for maximum thermal isolation. The 
sensing element and internal 
electronics are protected from the 
environment by a stainless steel case.
