Leybold PENNINGVAC PTR90 Combination Vacuum Gauge/Transmitter

The Leybold PENNINGVAC PTR 90 is a high-precision vacuum gauge/transmitter combining a Pirani sensor with a cold-cathode ionisation sensor in one unit. It is engineered for broad‐range pressure measurement from atmospheric down into the high vacuum regime (on the order of 10⁻⁸ mbar). Ideal for research labs, industrial vacuum systems, mass spectrometers, and process control applications, this gauge delivers reliable, stable measurements and advanced features (analog/digital outputs, setpoint relays, digital interfaces) for professional systems.

Key Features & Specifications

• Measurement range: from ~1 × 10⁻⁸ mbar up to ~1000 mbar (depending on version) in air/N₂.

• Dual‐sensor design: MEMS‐Pirani for higher pressures + cold-cathode (inverted magnetron) for lower pressures.

• Flange / connection variants: e.g., DN 25 ISO-KF (part no. 230 070), DN 40 ISO-KF (230 071), DN 40 CF-F (230 072)

• Electrical / communication options: Analog 0-10 V output, RS-232 or EtherCAT digital interfaces, multiple set-point relays (in “PTR 90 N” version)

• Robust design: The cold‐cathode cell ignition control is automatically managed by the Pirani sensor, protecting the lower sensor from damage at higher pressures.

• Operating conditions: Temperature +5 °C to +55 °C (storage –40 °C to +65 °C) typical. Storage and bake‐out limits apply.

• Weight: approximately 700 g (for DN 25 KF variant)

• Intended for inert/clean gases; not for flammable or combustible gases.

Application & Suitability

This gauge is highly suited for your target professional customers:

• Laboratory vacuum systems (research, analytical instruments) needing high vacuum monitoring.

• Semiconductor, thin‐film, coating, and surface science systems where accurate vacuum measurement across wide ranges is critical.

• Process and system control in industrial vacuum setups — the setpoint relay/digital interface versions support automated controls.

• Institutions requiring reliable measurement instrumentation with traceable performance and long service intervals.
