DatasheetDynisco PT4675 & PT4676 Melt Pressure Transmitters
Dynisco models PT4675 and PT4676 are amplified melt pressure transmitters designed for applications with limited installation space. The exposed 0.06" diameter capillary allows a bend radius of 1/16", making installation possible in very tight spaces.
Each transmitter includes a built-in amplifier and provides standardized voltage outputs for direct connection to DCS, computer or control systems. The devices offer adjustable zero and span settings, internal 80% shunt calibration and wetted parts made of DyMax™ coated 15-5 PH stainless steel.
