Televac MP7ER Cold Cathode Ionization Active Vacuum Gauge

Product catalog summary

Operating Specifications
The MP7ER Active Gauge operates within a range of 1*10^-8 Torr to 1*10^-2 Torr. It features an LED display and selectable analog output from 0 V DC to 10 V DC. The device includes one programmable set point with a relay, operates on a supply voltage of 22 V DC to 26 V DC, and consumes a maximum power of 5 W. Calibration is performed using dry air or nitrogen, and the gauge can withstand overpressure up to 150 PSI. It operates within a temperature range of 0 °C to 50 °C and can be stored between -20 °C and 60 °C. The bakeout temperature is 150 °C with electronics removed. The response time is ≤150 ms, and accuracy is ±0.2 decade from 1*10^-7 to 1*10^-2 Torr. The display is readable from a distance of 3 meters.

Ordering Information
The MP7ER is available with different output configurations and fittings. Part numbers vary based on the output type (logarithmic or linear) and fitting size (e.g., NW16, NW25, NW40, 2.75” CF). Replacement sensors and parts, such as the 7E Anode Assembly, are also available.

Description
The Televac® MP7ER Active Gauge uses a cleanable 7E double inverted magnetron cold cathode. It offers a wide measurement range, configurable analog output, and a programmable set point. The gauge is designed for use with MX2A and MX4A active gauges to provide full range vacuum measurement from 10^-8 to 10³ Torr, suitable for applications like heat treatment and vacuum furnaces.

Benefits
The MP7ER is cost-effective, compact, and features reliable cold cathode technology. It is easily cleaned, ensuring extended sensor life, and is supported by excellent customer service and rapid calibration turnaround.

Ratings and Compliance
The device is rated IP40 and includes a D-Sub 9-pin male electrical connection. It weighs 0.7 kg with the sensor and 0.3 kg without. Materials exposed to vacuum include stainless steel, ceramic, and fluoroelastomer.

Televac MP7ER Cold Cathode Ionization Active Vacuum Gauge-1

When combined with the MX2A or MX4A, the MP7ER will provide full range vacuum measurement from 10-8 to 1000 Torr. This is an optimal solution for heat treat and vacuum furnaces where calibration frequency requirements according to AMS 2769 vary between rough vacuum (MX2A and MX4A) and high vacuum (MP7ER) gauges. The Televac® MP7ER Active Gauge utilizes a cleanable 7E double inverted magnetron cold cathode. It has a variety of features including a wide range of measurement from 10-8 to 10-2 Torr, a configurable analog output, a programmable set point, and a bright LED display. The selection of fittings, simiplicity of use, ease of sensor cleaning, and low cost of the MP7ER make it an excellent choice for a variety of vacuum applications and industries. This gauge is designed for use with the MX2A and MX4A active gauges to provide full range vacuum measurement from 10-8 to 103 Torr. a. Heat treatment and vacuum furnaces b.
