Buying a key performance value (KPV) device is an investment in precision and reliability for professionals who demand consistent results from their analytical instruments. Whether you are a laboratory technician looking to upgrade your measurement tools, a quality control specialist needing more accurate readings, or an engineer seeking robust equipment for field applications, the KPV series offers a blend of advanced sensor technology, user-friendly interfaces, and durable construction that can meet diverse operational demands.
Key Features of the KPV Series
The KPV line incorporates state-of-the-art sensor arrays designed to deliver high sensitivity across a wide range of measurement ranges. The devices are equipped with built-in calibration routines, allowing users to perform zero checks and span adjustments directly on the instrument without external reference equipment. Many models feature multi-channel outputs that support both analog (4–20 mA) and digital (HART, Modbus, OPC UA) communication protocols, ensuring seamless integration into existing plant automation systems. The ruggedized housing protects against dust, moisture, and temperature extremes, making the KPV suitable for harsh industrial environments as well as controlled laboratory settings.
Lab Test Reports
To provide confidence in performance, each KPV unit undergoes a comprehensive series of lab tests before shipment:
Accuracy Assessment: Using traceable standard gases and liquids, the device is measured against certified reference materials. Results show an average deviation of less than 0.5 % from nominal values across all operating ranges.
Stability & Drift: Long-term stability testing over 100 hours at constant temperature revealed a drift of no more than 0.02 % per hour, meeting the stringent requirements for continuous monitoring applications.
Temperature Compensation: Devices were exposed to temperatures ranging from –20 °C to +70 °C while measuring a fixed pressure value. The output remained within ±0.1 % of the true value across this temperature span.
Hygroscopic Resistance: Humidity tests at 95 % relative humidity for 72 hours confirmed no degradation in sensor response, verifying the sealed design’s effectiveness against moisture ingress.
Mechanical Shock & Vibration: Standard shock tests (up to 20 g) and vibration profiling (10–500 Hz) were performed to emulate transportation and field deployment scenarios. The KPV units maintained full functionality with no loss of accuracy.
These lab test reports are available upon request in PDF format or can be viewed on the manufacturer’s website under the "Technical Documentation" section for each model.
Frequently Bought Together
Customers who purchase a KPV device often find additional accessories and complementary products that enhance performance and simplify installation. Popular bundles include:
Calibration Kit: A set of standard calibration gases (e.g., 0 psi, 50 psi, 100 psi) and liquid reference solutions that allow quick, on-site recalibration.
Cable Assemblies: High-quality twisted-pair shielded cables for HART or Modbus communication, pre-terminated to reduce installation time.
Mounting Brackets & Enclosures: Stainless steel brackets designed for DIN rail mounting, along with weatherproof enclosures that protect the unit in outdoor settings.
Software Suite: License for the KPV configuration and monitoring software, which provides a graphical interface for data logging, trend analysis, and remote access.
Replacement Parts Pack: Includes spare sensors, connectors, and filters to ensure uninterrupted operation during routine maintenance.
These bundled items are priced with volume discounts and can be purchased together at checkout. They help users achieve optimal performance from the KPV right out of the box while minimizing downtime and setup complexity.
