Joysticks keep ROVs in control
Aberdeen based Sub-Atlantic Limited are using two different Penny and Giles joysticks for motion control on their Apache and Cherokee ROVs.
The use of surface mount components and modern microprocessor technology has enabled powerful features to be packed into a standard 1/8 DIN case, with measurement performance significantly better than other indicators in their price range.
The four models can be used for both simple 'measurement only' applications and in more demanding situations requiring digital communications, alarms, maths functions and complex signal conditioning.
The powerful menu-driven software enables fast flexible set-up from the front panel or via the serial communications interface.

Sensors give accuracy on web tensioning
Penny and Giles HLP190s (Hybrid Linear Potentiometers) are specified by Valmet Atlas-Winders for the web tensioning systems on their range of paper, film and textile unwind and rewind machines.
No adjustment of internal trim pots, internal links or plug-in cards is necessary.
The DMP200 series is ideally suited to operate with Penny & Giles linear and rotary potentiometers, providing a 10 Vdc or 0 -12 Vdc transducer supply.
The DML300 series of digital panel indicators is designed specifically for use with LVDT transducers.
The "Fast-Cal" feature provides a fast and simple means of calibrating an indicator to the transducer at any two stroke positions.
The DML300 is configured for the correct transducer excitation voltage and frequency as recommended by the sensor manufacturer.
As LVDT transducers 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.
The measured LVDT signals values are then stored, with their relevant display values, as the calibration parameters.
The DML300 can also automatically set the correct input gain to suit the LVDT transducers output.
The displayed values can be in millimetres, inches or any other measurement units.
DML300 series indicators have a five digit display, transducer excitation supply and many software features including max/min memory and maths functions.
All models are fitted with two analogue outputs - a high speed analogue output for monitoring fast changes of sensor movement, and a separate, electrically isolated, scaleable analogue output.
The serial RS 422/485 communications interface allows connection to data loggers, PLCs and computers.
Two logic inputs are provided to allow remote control of user selectable functions.
In addition, two of the front panel push-buttons can be user defined to allow fast access to pre-programmed functions.
All three models share the basic DML330 specification.
In addition the DML340 has two alarm relays and the DML350 has four TTL alarm outputs. Request a free brochure from Penny + Giles ...
