Compact, High Precision Pressure Transducer Model KPK
Description
The KOBOLD KPK Compact Pressure Transducer is designed to deliver
high performance at an economical price. Utilizing either thin-film or
piezoresistive technologies, the KPK series offers precision, shock
resistance, and long term sensor stability. Noise immunity is assured
by compliance with the IEC 801 standard (CE compliant). Installation is
simplified by providing protection against common installation mistakes
such as reverse polarity wiring, overvoltage and short circuiting. All
KPK sensors undergo inspection and testing to assure a trouble-free
installation.
Applications:
• Hydraulic and Pneumatic Systems
• Industrial Machinery and Machine Tools
• Injection Molding Machines
• Stamping and Forming Processes
• Pumps and Compressors
• Laboratory and Test Equipment
• HVAC Systems
• Refrigeration Equipment
• Petrochemical
