Instruction PST4K 9K4

Product catalog summary

Technical Specifications:
The Picostat models 9B4, 9K4, and 9M4 have varying operating and media temperature ranges. Standard operating temperatures range from -25°C to +125°C, with specific sensors allowing for a range from -40°C to +125°C. The electrical connections and measuring ranges are specified, with resistive and inductive load ratings provided for different voltage levels.

Electrical Connections and Ratings:
The document details the resistive and inductive load ratings for silver and gold-plated contacts across various AC and DC voltages. For example, silver contacts are rated at 250 V AC with a load of 6 (1) A and 24 V DC with a load of 3 (2) A.

Switching Differential and Pressure Ranges:
The switching differential is a fixed value and not adjustable, with specific values provided for different pressure ranges. The document lists pressure ranges in both bar and psi for microswitches and sensors, including bellows, piston, and membrane sensors.

Dimensions and Adjustment:
Dimensions for the Picostat models are provided, along with instructions for switching point adjustment. The document includes specific measurements and torque requirements for pressure connections and fastening screws.

Important Notes:
Attention is drawn to the hysteresis depending on the preset value, and specific torque values are provided for various components, such as the pressure connection and fastening screws.
