Thermo-Serv PHP601 manual Temperature measurement, RTD measurement

Temperature measurement .....................................................................................

Direct reading in mV or °C, °F or K.

-From 1 to 4 calibration points may be entered for all types of sensors.

-Digital filter.

-Programming using either the RS 232 link (standard) or the IEEE 488 link (option).

-Direct control of the SHP 101 scanner.

-Storage of up to 5000 measurements together with date.

-Measurements triggered by internal or external event.

-2 alarm outputs relays.

RTD measurement .................................................................................................

Measurement of all types of sensors as described below:

-Standardized sensors according to IEC

Publication 751/1995,

α = 3851, Pt 100, 200, 500 and 1000.

JISC 1604/1989, a = 3912, JPt 100. EIT 90, α = 3926, Pt 100.

DIN 43760, α = 618, Ni 100. MIL-T 24388C, α = 672, Ni 120. MINCO 16/9, α = 427, Cu 10.

-Callendar and Van Dusen equations defined by coefficients (Ro, A, B, C) or by 4 couples of points (resistance/tempera- ture).

-EIT 90 equations defined by R at 0.01°C and the deviation function coefficients or by resistance values at fixed points.

-Polynomial equations defined per point (25 points max.).

For sensors not complying to the International Temperature Scale (ITS 90) correction of the deviation ITS 90-IPTS 68, 1993 is applied.

Choice of 6 measuring currents (0.125 up to 4 mA), 3 current waves (direct, pulse and alternate) together with I/V2 function to define self-heating measurement.

3 or 4 wire configuration.
