Instrotech’s multi-function weighing transmitter technology

Instrotech has on offer the multi-function weighing transmitter, the DPM6004MFl. It’s a powerful, compact, field-mounted unit that can be selected for a variety of weighing functions.

DPM6004MFSpecifically designed for servicing organizations, weighing equipment manufacturing companies and individual users, the DPM6004MF is a single electronic unit that can be used for almost any application in the weighing industry. The DPM6004MF finds application in the areas of loadcell transmitting, belt-weighing, loss-in-weight transmitter, through-put weighing, bag-filling, batch-weighing and a dynamo meter. A multi-function unit allows the user to keep one spare that can replace any of the above-mentioned functions in the field. This also reduces the stock holding requirements for manufacturers, integrators and factories.

Version ll of the DPM6004MF  has an improved and simplified user menu interface and operation service manual, as well as much improved EMI immunity. Design technicians have also improved on the standard SD card functionality for fast on-site internet software upgrades with remote registration. While busy, they also vastly improved the on-board Pl control and the on-board system diagnostic information and simulation.

The DPM6004 range consists of three models, the DPM6004LC is dedicated to standard load cell applications, the DPM6004BW dedicated to belt weighing applications and the DPM6004MF that is a multifunction unit.

Standard features include:

  • Rugged, powder-coated, cast aluminium housing with splashproof keypad
  • Inputs from a load cell, incremental encoder & six digital
  • Programming via keypad and LCD display
  • User-programmable function keys, digital inputs and relay outputs
  • 15 point lineariser, min/max hold, auto-zero maintenance, preset tare
  • PI control with auto-manual set points
  • Outputs for isolated analogue 1-5/0-10Volts or 0/4 - 20mA
  • Data logging via SD card

When used specifically for the bulk handling industry, the DPM6004MF can be used in conjunction with Instrotech’s range of fully hermetically sealed, stainless steel load cells from Vishay Revere Precision Group. The Revere bending beam load cell, the model SHBxR, is particularly suitable for low capacity platform scales, packaging machines, belt-weighers, hybrid scales and process weighing applications.

Suited to capacities of 5 to 350kg, the SHBxR load cell is a fully-welded construction and water block cable entry ensures that it can be reliably used in tough environments found in food, chemical and process industries. For intrinsically safe and/or potentially explosive atmospheres the load cells are available with both local and international ATEX approval.
