Verified by Europages badge

Peter Hirt linear ball bearings adapted to be play-free. The components of linear ball bearings, including shaft, ball cage and housing, are individually lapped and honed together in matched sets for each individual linear ball bearing. This ensures no stick-slip effect and maximum lifetime values. Peter Hirt thread gauge feelers are available from the smallest size of 0-200 (ball diameter 0.200 mm) up to size 12 (ball diameter 4.000 mm). The smallest thread gauge feeler at present, size 0-200 with a ruby ball diameter of 0.200 mm, is sized for measuring threads up to size M1.7. The thread gauge feelers are available individually or in a protective wooden box as a 12 pc, 13 pc or 14 pc set. Signal conditioning modules from Peter Hirt are specially calibrated for T-series tranducers with TESA® compatible half-bridge circuit. Modules are available with supply voltages of 5, 12 or 24 VDC and with a bipolar or unipolar output signal of ± 5 VDC, ± 10 VDC, 0-5 VDC, 0-10 VDC

    The pressure transmitters of the 4LD series use the chip-in-oil technology developed by KELLER, uniting a pressure measuring cell, digital temperature compensation and signal processing in a compact housing made of stainless steel or Hastelloy. The transmitters are extremely resistant to environmental influences and delivery highly accurate measurement results as a digital output signal. The I2C interface and the low supply voltages make it easy to integrate in microcontroller-based systems. The extremely low power consumption is ideal for battery-operated devices. The D line is perfect for IoT solutions.

    The differential pressure transmitters of the PRD-33X series are designed for accurate measurements in low pressure ranges with very high overload on both sides. In addition to the differential pressure sensor, which may only be exposed to gases at its rear face, the devices have an additional absolute pressure sensor that measures the line pressure. Both measured values are output via the digital RS485 interface and are the ideal basis for cryogenic tank monitoring.

    The differential pressure transmitters of the PD-23 series are designed for industrial applications and are supplied with a G1/4 internal thread as standard. They are based on a fully analog circuit. The PD-23 transmitters have a single silicon diaphragm in their interior, which is pressurised from both sides and measures the pressure difference directly. This design enables them to measure tiny pressure differences even at an extremely high line pressure.
