Custom calibration to
customer specifications can be
added as a separate line item
at time of purchase.
Optional factory calibration to customer specifications is ordered as a separate line
item at time of purchase, and on a per unit basis. Factory calibration will require the
specification of input type, input range zero, input range full-scale, Steinhart-Hart or
Beta constants for Thermistor input types, and output range. Normal or reverse
acting output and a filter level can also be specified. Use form 8500-858 for
specifying this calibration from our web site at www.acromag.com.
The standard model without adding custom factory calibration is calibrated by
default to reference test conditions. Recalibration of any transmitter will require use
of a TTC-SIP configuration kit, ordered separately (see Accessories section). Modules
can be mounted on standard 35mm “T” Type DIN rail.
Input
Input Reference Test Conditions:
100Ω Pt RTD, α = 0.00385;
-200°C to 850°C input;
Configuration = Three-wire; Filtering = Medium; Output = 4 to 20mA, ascending; R-
Load = 250Ω. Break detection = Over
-range; Ambient = 25°C; Power supply = 24VDC;
Input Configuration:
Four-wire (lead-wire has negligible effect), three-wire with
lead-wire compensation, and two-wire without lead-wire compensation.
Input Impedance:
15.4M
Ω typical.
Input Overvoltage Protection:
Bipolar Transient Voltage Suppressors (TVS) rated up
to 5.6V working voltage, typical. Also includes capacitive filtering, and series
resistance.
Input Filtering:
Normal mode RC filtering, plus digital filtering, optimized and fixed
per input range and filter selection within the
-
ADC. See Normal Mode Noise
Rejection and Output Response Time.
Input Excitation Current:
Set to 0.1mA, 0.2mA, 0.5mA, 1mA typical, for Inputs
1000Ω, 500Ω, 200Ω, 100Ω & Nickel &
Copper respectively. Drift over temperature
has negligible error contribution due to ratiometric measurement technique.
Input Response Time:
See output response time.
Input Linearization (RTD Inputs):
Preset for input.
