Nominal Resistance
In accordance with DIN EN 60751, the nominal resistance is
defined as follows:
. 100 O RTD at 0 °C
. Temperature coefficient a = 0.00385 O x °C/O), averaged
between 0 and 100 °C
Limit Deviations
Tolerance Class A as standard: t = ± (0.15 + 0.002 x t);
valid for the complete temperature range from -50 to +450 °C
Lead Wire Configuration
As single element (1Pt 100) with 3 or 4 lead wires or dual element
(2Pt 100) with 3 lead wires
Response Time
Less than 12 seconds to reach 63% step change in water flowing
at 0.4 m/s
Process Temperature Range
-50 to +450 °C
The measurement range can be limited by the gasket in the
process connection.
Ambient Temperature
Housing without head-mounted transmitter
. Metal housings: -40 to +130 °C
. Plastic housings: -40 to +85°C
Housing with head-mounted transmitter
. -40 to +85°C
Maximum Process Pressure
Lower maximum pressure can be due to the process connection
Pressure ratings at 20 °C:
. Tri-Clamp: 10 bar
. Weld-in Ball with PEEK-Seal: 6 bar
. Weld-in Ball with SST-Seal: 40 bar
. Threaded: 40 bar
. Tapered Union with Coupling Nut: 10 bar
Shock and Vibration Resistance
According to DIN EN 60751: 2.8 g peak / 10.500 Hz
Self Heating
0.15 °K/mW when measured per method defined in DIN EN 60751
Insulation Resistance
1,000 MO minimum insulation resistance when measured at 500
Vdc and at room temperature
Sheath Material
321 Stainless Steel with mineral-insulated cable construction
Lead Wire
PTFE insulated, silver coated copper wire
Identification Data
The model and serial numbers are marked on each sensor
Ingress Protection (IP) Ratings
The particular rating is applicable only for complete assemblies
including a connection head and tubular thermowell. IP varies from
65 to 68 due to a wide selection on different connection heads,
DIN A and B size, made of different materials such as aluminium,
polyamide and stainless steel
