Checkline PD765-6R3-20 Digital Tension Indicator 4-Digit Display

The Checkline PD765 Digital Indicator is designed to work with Check-Line tension sensors providing a large, bright LED display of real-time tension values. It is easy to set up and permits flush panel mounting in a 1/8 DIN cutout. The PD765-6R3-20 offers 4-20 mA output for external recording and data-logging purposes. Hi/Lo limits and relay contacts can be optionally specified on PD765-6R5-10 supplied instead of the 4-20 mA analog output. The standard model PD765-6R3-20, operates from all worldwide AC-Power (85-265V AC). 0-10V DC output is not available

Features

Can be scaled to any engineering units desired with user-set decimal point.
4-20 mA analog output for recording and control purpose (No analog output provided on PD765-6R5-10)
Requires 85-265V AC Power, provides regulated power for the tension sensor
Hi/Lo Limits and relay contacts provided on PD765-6R5-10 (supplied instead of 4-20ma output)
User-set filters can be used to adjust signal sensitivity to reduce fluctuations of tension values
