SICK: New PTA Series – Pressure Sensors
February 5, 2026
New PTA Series: High-Quality Pressure Sensor Family for Demanding Tasks
The PTA series products comprise high-quality and versatile pressure sensors for measuring the pressure of liquid and gaseous media. The sensors are available as PTAC with a capacitive ceramic measuring cell or as PTAM with a fully welded stainless steel measuring cell. Thanks to flush-mounted connection options, even viscous and sticky media pose no problem.
Appropriate variants are available for hygienic applications and use in explosion-hazardous areas. With the optional IO-Link and WPAN interfaces, the PTA can be easily integrated into digital system environments and provides reliable print data for automated systems. The Smart Assistant app from SICK makes location-independent commissioning, adjustment and diagnostics easier.

Advantages
The Right Fit for Custom Applications
Whether as a PTAC with capacitive ceramic measuring chamber for applications with high overload safety, or as a PTAM with stainless steel diaphragm for high pressures and hygiene applications: The two product families of the PTA sensor offer a high degree of flexibility. Thanks to different process connections, outputs, measuring chamber options, optional explosion protection and more, the pressure sensors can be individually adapted to the particular requirements on site – without having to resort to different sensor systems or manufacturers. The PTA meets the requirements of demanding industries such as mechanical engineering, the pharmaceutical industry, battery manufacturing and food production.
Two Measuring Chamber Options for Versatile Use
The PTA pressure sensor family has two measuring chambers with which a wide range of applications can be individually realized. As a PTAM, the sensor has metallic measuring chambers with hygiene approvals, which are also designed for high pressures. In the PTAC version, a capacitive ceramic measuring chamber is integrated into the pressure transmitter, which eliminates any potential risk of contamination due to its transmission medium free design. Regardless of the choice of measuring chamber, no residues are deposited on the sensor head thanks to dead space-free and hygienic process connections – ensuring reliable data delivery.
