Based on a silicon piezoresistive sensor and electronic module with an active temperature compensation technology it features exceptional accuracy and response time. APZ 3421 has a wide variety of optional features such as display and digital interfaces to suit almost any of the high precision measurement applications.

PIEZUS - Model APZ 3420 m - Pressure transmitter with flush diaphragm for viscous media

APZ 3420 m is a flush diaphragm version of our standard pressure transmitter. Due to it’s optimized design, it does not have dead zones that can get blocked by the viscous and pasty media. Optionally, APZ 3420 m can be equipped with a heat sink element for high temperature media applications.

PIEZUS - Model APZ 3420 s - Sanitary pressure transmitter with flush diaphragm

APZ 3420 s is a sanitary version of our standard pressure transmitter with the flush diaphragm . All-welded design and smooth surfaces ensure absence of zones for potential contaminants collection. Process connection options, taper socket with grooved union nut as per DIN 11851, clamping socket as per DIN 32676 provide for quick disconnection for diaphragm cleaning. Optionally, APZ 3420 s can be equipped with a heat sink element for high temperature media applications.

PIEZUS - Model APZ 3410 - Industrial pressure transmitter for aggressive/viscous/abrasive media

APZ 3410 is based on a ceramic oil free sensor to withstand aggressive(*) media. Optionally, plastic process connection is available for certain alkalis and acids. Flush ceramic diaphragm and the open port options are available for the viscous and/or abrasive media. Oil free dry pressure cell makes APZ 3410 suitable for environments with high oxygen levels and allows to measure gases with high O2 concentrations. (*) please consult the manufacturer for particular media compatibility

PIEZUS - Model APZ 3240 - Precision pressure transmitter for aggressive/viscous/abrasive media

APZ 3240 is based on a high precision capacitive ceramic oil free sensor with ranges starting at 40 mbar for measuring liquid levels as low as 40 cm. Flush ceramic diaphragm makes it a perfect fit for the viscous, aggressive(*) and abrasive media. Optionally, plastic pressure port is available for certain alkalis and acids. Oil free dry pressure cell makes APZ 3240 suitable for environments with high oxygen levels and allows to measure gases with high O2 concentrations.
