This conditioner is for high-accuracy temperature measurement using platinum
Resistance Temperature Detectors (RTD's), either DIN (European) or American
standard. Precision constant-current excitation is provided for four independent sensor
channels, which may be intermixed as required. RTD inputs are normally set for four-wire
cabling, with maximum excitation of one milliampere and input impedance of 10
megohms, to eliminate common self-heating and cable-loading errors. However, for an
RTD channel with shared current return and sense signals, three-wire mode is available,
if desired, via an internal jumper setting.Calibration of the 10A16-4C may be either
- "absolute" for RTD's of DIN standard (only), or
- "two-point" (i.e., "zero and span"), when independently and accurately known temperature references are available- preferably the high and low extremes to which the sensor will be subjected.
- RTD Types: Platinum; DIN (European) standard with "ice-point" resistance of 50, 100, or 200 ohm, or American standard with "ice-point" resistance of 100 ohm
- Range and Resolution: See Table below; automatically selected- on an individual channel basis- when the channel is configured
- Linearization: Internal digital linearization; maximum error: ±0.1° C (±0.2° F), System 10 and SPS8000
- Excitation (per channel): Nominal 5 V-DC; 1 mA, maximum
- Amplifier (per channel):
