Televac's 1E and 1F piezo diaphragm vacuum sensors provide a range of measurement and are suitable for multiple gas and/or mixed gaseous environments. The direct, gas-independent sensors offer fast response time, are stable with an accuracy of ±5%, and feature nickel-plated brass or stainless-steel bodies with a choice of connections. The 1E sensor provides a vacuum range of 1 to 1000 mmHg (0.133 to 133 kPa) while the 1F provides 1 to 7600 mmHg (0.133 to 1013 kPa). Both can be used with the company's MM200 dual-display, half-rack, microprocessor-based modular vacuum gauge, which can be configured to include various combinations of hot and cold ionization, thermocouple, convection, diaphragm, set point relays, and digital communications. Applications include heat treating, coating processes, electron beam welders, and conveying.
