Core offering

KELLER Pressure manufactures and sells piezoresistive pressure transducers and transmitters, level probes, data loggers, digital pressure gauges, wireless remote transmission solutions, and customer-specific custom pressure sensor solutions. Its PressureSuite software (Cloud and Desktop) supports configuration and data analysis for these products. The company produces more than 1.3 million pressure measuring cells annually, covering pressure ranges from 5 mbar to 2000 bar at accuracy of 0.01% of full scale.

Product overview

KELLER Pressure is a Swiss manufacturer of high-precision piezoresistive pressure measurement technology. The product portfolio centers on seven core product categories: Pressure Transducers (encapsulated sensors forming the core measurement element), Pressure Transmitters (transducers with integrated electronics for signal compensation), Level Probes (submersible probes for liquid level measurement), Data Loggers (for recording pressure and temperature profiles), Digital Pressure Gauges (with display), Wireless Solutions (for remote data transmission via LoRa/2G/3G/4G/NB-IoT/LTE-M), and Custom Solutions (customer-specific modifications). Supporting these products are Software & Accessories including PressureSuite (Cloud and Desktop) software for configuration and data management. Key product lines include the ARC1 autonomous remote data collector family, Series 36XW-CTD multi-parameter probes for water analysis, and Series 26KyX level probes with Kynar diaphragms. The company also offers specialized hydrogen-compatible variants across multiple product lines. All products are developed and produced at facilities in Winterthur, Switzerland, with pressure ranges from 5 mbar to 2000 bar.

Direct peers

• VEGA Grieshaber: VEGA is a German family-owned specialist in level, switching, and pressure measurement with strong credentials in water, wastewater, and process industries. Its pressure and level sensor families directly overlap with KELLER Pressure's level probes and pressure transmitters in similar end-customer use cases.
• Kistler: Kistler is a Swiss precision sensor specialist focused on dynamic pressure, force, and acceleration measurement. It is both an explicit distribution partner of KELLER Pressure in China (per company data) and a complementary peer in high-precision industrial and test/measurement applications.
• Endress+Hauser: Endress+Hauser is a Swiss-German process instrumentation specialist offering pressure, flow, level, and analytical measurement for industrial customers. Its Cerabar and Deltabar pressure product lines compete head-to-head with KELLER Pressure's transmitters in water, oil and gas, chemical, and food/pharma applications.
• WIKA: WIKA is a global leader in pressure, temperature, force, and level measurement with a comprehensive industrial sensor portfolio serving the same automotive, oil and gas, water, and process-industry customers as KELLER Pressure. As a German-based family-run industrial sensor specialist of comparable size, it is the closest direct competitor.

Emerging players

• IFM Electronic: IFM Electronic is a German industrial sensor manufacturer offering pressure, level, and flow sensors with strong IO-Link connectivity for factory automation. It represents an emerging player connecting pressure sensing into smart-factory and IIoT contexts where KELLER Pressure is expanding with its IO-Link variants.
• Baumer Group: Baumer is a Swiss family-owned sensor and instrumentation group with pressure, level, and process sensor offerings. It is comparable as another Switzerland-based, family-run sensor specialist targeting similar industrial OEM and process customers.

Broad incumbents

• ABB Measurement & Analytics: ABB's pressure, flow, and level instrumentation competes with KELLER Pressure in process industries, power, and water utilities. ABB's scale and global service network make it a broad incumbent alternative for similar accuracy-grade pressure and level applications.
• Yokogawa Electric: Yokogawa's industrial automation and process instrumentation portfolios include pressure transmitters used in oil and gas, chemical, and power. It is a broad incumbent with strong Asia-Pacific presence that overlaps with KELLER Pressure's regional subsidiaries in Japan, China, and Singapore.
• Honeywell International: Honeywell's process measurement and control portfolio includes pressure transmitters and sensors used across refining, aerospace, and industrial automation. The breadth and aerospace pedigree of Honeywell make it both a competitor and a reference benchmark for KELLER Pressure's high-precision and aerospace-grade products.
• Emerson (Rosemount): Emerson's Rosemount division is a dominant industrial pressure and process instrumentation player, with deep reach into oil and gas, chemical, and power customers. It is a broad incumbent that competes with KELLER Pressure particularly in refinery, pipeline, and large-scale industrial deployments.
