LVDT input Indicators - DML300 series

?‘Fast-Cal’ calibration?Adjustable display resolution?Maximum / minimum memory?Isolated analogue output?Two logic inputs?Front panel function buttons?Transducer excitation supply?High speed analogue output?Universal mains power supply?Serial communications?Dual alarm relays?Quad TTL alarm outputs?Compatible with Penny & Giles LVDTs The DML300 series of digital panel indicators are designed for use with LVDTtransducers. They are ideal for industrial and test applications and feature a fivedigit variable brightness LED display, a fast (125Hz) unscaled analog output formonitoring fast changes, a separate electrically isolated 0-10 Vdc/4-20mAscaleable output, serial 2 or 4 wire RS 422/485 communications interface, twologic control inputs to allow remote control of user selectable functions and twofront panel push buttons that can be user defined to allow fast access to pre-programmed functions. The ‘Fast-Cal’ feature provides a fast, simple method ofcalibrating an indicator to the transducer at any two stroke positions. As LVDTtransducers can only be calibrated in situ, the sensor is set to the mechanical low(zero) and then the high (span) positions when prompted by the DML300. Themeasured LVDT signal values are then stored, with their relevant display values, as thecalibration parameters. The DML300 also automatically sets the correct input gain tosuit the transducer output. Displayed values can be in any measurement units.

Clear display Front panel control Total reliability

The flat, slightly recessed high brightness LED display, ensuresmaximum visibility even indifficult ambient conditions. Set-up is facilitated by the front panel buttons and a password protectedmenu. Two of the buttons can be userprogramed to provide one or morespecial functions. Surface mount andmicroprocessor technology has enabled powerful features to bepacked into a 1/8 DIN case. No maintenance is necessary.
