High Accuracy Heavy-Duty Pressure Transducer Model KPG

Description

KOBOLD KPG series transducers are designed for heavy duty
applications requiring high accuracy. Utilizing either advanced diffused
semi-conductor or sputtered thin film technology, the KPG achieves
accuracies of ±0.125% at pressures up to 145,000 PSIG. It offers
shock resistance, extreme long term sensor stability, and excellent
noise immunity (CE compliance). The KPG also offers protection
against common installation problems such as reverse polarity wiring,
overvoltage, and short circuiting.

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
