PX309 Pressure Transmitter
General-purpose 4-20 mA pressure transmitter.

4" industrial gauge with 316 SS wetted parts, ±1% Grade 1A accuracy.
The Miljoco P4098LY-SS is a 4" dial industrial pressure gauge with 300 series stainless steel case and 316 stainless steel wetted parts. Field liquid-fillable with glycerine (PLF4098LY-SS) or silicone (PSF4098LY-SS), it delivers Grade 1A accuracy for general industrial processing applications.
Process pressure deflects a 316 stainless steel Bourdon tube, driving a micro-adjustable aluminum pointer across a white-finished aluminum dial via a stainless steel rotary movement.
