Product catalog summary

Operating Specifications
The MP7FR Active Vacuum Gauge operates within a range of 1*10^-11 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 can be done using dry air or nitrogen, and it can withstand overpressure up to 150 PSI. The gauge operates within a temperature range of 0 ºC to 50 ºC and can be stored between -20 ºC to 70 ºC. The bakeout temperature varies depending on whether electronics and magnets are removed, with a maximum of 400 ºC. The response time is ≤150 ms, and accuracy is ±0.2 decade from 1*10^-9 to 1*10^-2 Torr. The display is readable from a distance of 3 meters.

Ordering Information
The MP7FR is available with different logarithmic outputs and stainless steel configurations. Replacement sensors and various cable lengths are also available. A wall power supply for USA standards is offered.

Description
The Televac® MP7FR utilizes a 7F double inverted magnetron cold cathode passive vacuum gauge. It is designed for a wide range of vacuum applications, offering simplicity, a wide measurement range, and cost-effectiveness. It can be used with MX2A and MX4A gauges for full range vacuum measurement.

Applications
Suitable for national labs, universities, research and development, and thin film deposition and coating processes.

Benefits
The MP7FR offers low cost, compact design, reliable technology, excellent customer service, and rapid calibration service. It is designed and manufactured in the USA.

Ratings and Compliance
The device is rated IP40.

Electrical Connections
The gauge uses a D-Sub 9-pin male connector with specific pin assignments for sensor voltage control, supply voltage, analog output, and set point relay connections.

Set Points
The MP7ER has one set point using a Form C contact relay with specific rated loads and maximum switching voltages.

Physical Characteristics
The enclosure is made of aluminum, and the device weighs 1.0 kg with the sensor. Materials exposed to vacuum include stainless steel and ceramic.

Catalog excerpts

When combined with the MX2A or MX4A, the MP7FR 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 vary between rough vacuum (MX2A and MX4A) and high vacuum (MP7FR) gauges. The Televac® MP7FR Active Vacuum Gauge utilizes a 7F double inverted magnetron cold cathode passive vacuum gauge. It has a variety of features including a wide range of measurement from 10-11 to 10-2 Torr, a configurable analog output, a programmable set point, and a bright LED display. The simiplicity of use, wide range of measurement, and low cost of the MP7FR 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 10-11 to 103 Torr. a. National labs, universities, and research and development b.
