Both technologies can be acclimated
6 axis force sensor and eddy-current probes accept altered operating temperature ranges. Eddy-current probes, because of their altruism of adverse environments accept a greater temperature range. Accepted eddy-current probes, which use polyurethane cables, accept an operating ambit from -25 to +125°C. Top temperature probes, which use teflon FEP cables, accept an operating ambit of -25 to +200°C. Capacitive probes, which are afflicted by condensation, abandoned accept an operating ambit of +4 to +50 °C. The disciplinarian electronics for both analysis technologies accept an operating ambit of +4 to +50°C.
Both technologies can be acclimated in exhaustion applications. Abstracts in the probes are alleged for structural adherence and minimized outgassing beneath vacuum. Exhaustion accordant probes are subjected to an added charwoman action and adapted packaging to abolish adopted abstracts that may abuse a aerial exhaustion environment.
Many exhaustion applications crave complete temperature control. The probe's adeptness consumption, with its associated accession to temperature change, is breadth capacitive and eddy-current technologies differ. A capacitive delving has acutely baby accepted breeze and adeptness consumption. A archetypal capacitive delving consumes beneath than 40µW of power, accidental complete little calefaction to the exhaustion chamber.
The adeptness burning in an eddy-current delving can alter from multi axis load cell to as top as 1mW. At these college powers, the eddy-current delving will accord added calefaction to the exhaustion alcove and could afflict high-precision exhaustion environments. The adeptness burning in an eddy-current delving is abased on abounding factors; delving admeasurement abandoned is not a acceptable augur of adeptness consumption. Anniversary eddy-current sensor's adeptness burning accept to be adjourned individually.
Either capacitive or eddy-current sensors can plan able-bodied in exhaustion environments. In temperature acute vacuums, eddy-current sensors may accord too abundant calefaction for the application. In these applications, capacitive sensors will be a bigger choice.
Because of thru-hole load cell in the appearance and acknowledging attributes of the analysis fields of capacitive and eddy-current sensors, the technologies accept altered delving ascent requirements. Eddy-current probes aftermath analogously ample alluring fields. The acreage bore is at atomic three times aloft than the delving bore and greater than three diameters for ample probes. If assorted probes are army abutting together, the alluring fields will interact. This alternation will actualize errors in the sensor outputs. If this blazon of ascent is unavoidable, sensors based on agenda technology such as the ECL202 can be distinctively calibrated to abate or annihilate the arrest from adjoining probes.
