Specifications

Typical specifications for standard targets and probes. Actual values depend on probe, target, and calibration.

Resolution: RMS at mid-range for most calibrations. See Ranges below for resolution details.	DC-10kHz - 0.02% of range RMS
Nonlinearity	See Output Curves in Range/Probe Section Below
Temperature Drift of Probe at mid-range	±0.1% of range/°F ±0.2% of range/°C
Voltage Output	Analog Voltage: 0-10V
Switch Output	Switch closure when output voltage is above adjustable threshold: 48VAC/70VDC/100mA
Input Power	12-24VDC 130ma @ 15V
Operating Temperature	40°F-120°F 4°C-50°C
Probe Operating Temperatures	Standard Probes: -10°F-+250°F -25°C-+125°C High Temperature Probes: -10°F-+400°F -25°C-+200°C

Ranges/Probes

A specific range and resolution will require a particular probe size/model. Range/Resolution may also be affected by the target material.

Probes are identified by their internal coil diameter.
A U5 probe has a 5mm coil, U8 a 8 mm coil etc. Larger ranges require larger coils/probes.

Custom ranges are always available.

Listed specifications are for standard target materials.
