Q: You offer two versions – industrial stability and high stability - of the DSC and DCell, what is the difference?

A: The Industrial Version offers 25ppm basic accuracy (equates to 16 bit resolution). The High Stability version offers 5ppm basic accuracy (equates to 18 bit resolution) with comparable stability which far exceeds standard instrument performance.

Q: Are the devices low-power?

A: Yes, low-voltage DC supply (5.6V min), typically 40mA for RS485 &.52mA for RS232 (including 350R strain gauge).

Q: How about multiple output options?

A: We offer a choice of two communications standards: RS232 (DSC only) or RS485, with a choice of three different protocols: ASCII, MODBUS or MANTRABUS, for ease of integration. All variants provide identical features and performance.

Q: Is there adjustable sensitivity?

A: Yes, the devices can be configured for standard 2.5mV/V full-scale strain gauges as supplied. A single additional resistor configures the input between 0.5 and 100 mV/V full-scale.

Q: Do you offer linearity compensation?

A: Yes, advanced 7-point linearity compensation.

Q: Is there options for serial output and how many devices can be used on a bus?

A: Yes the DSC products offer lower-cost cabling, improved noise immunity, and longer cable runs with no accuracy penalty. Device addressing allows up to 253 devices on a single bus, drastically reducing cabling cost and complexity. Two-way communications allow in-situ re-calibration, multiple outputs and diagnostics. No separate measuring instruments needed.

Q:How do you calibrate?

A: We offer digital calibration which is completely drift-free, adjustable in-system and/or in-situ via standard communications link. Two independent calibration stages for load cell-and-system-specific adjustments. Programmable compensation for non-linearity and temperature corrections. Calibration data is also transferable between devices for in-service replacement.

Q: Are there self-diagnostics?

A: Yes, the devices offer continuous monitoring for faults such as strain overload, over/under-temperature, broken sensors or unexpected power failure. All fault warnings are retained on power-fail.
