Need to Customize Your Assembly - Fine Tune the Part Number:
After locating a figure and part number, you can fine tune the sensor for your application. If you require an American curve
sensor and not the European curve, change the “
E
” to an “
A
” in the part number. If you require a 500
Ω
and not the standard
100
Ώ
sensor, change the “
11
” in the part number to “
51
”. 1000
Ώ
sensors can be ordered by changing the “
11
” to an “
101
”.
Substitute any “
X
” and “
Y
” characters with your length requirements. RTDs are provided in four wire configurations as standard.
This is the most accurate configuration.
Note:
if you are using a transmitter you may be only able to use a three wire sensor.
This can be designated by changing the “
4
” in the part number to a “
3
”. Two wire RTDs can be specified by changing the “
4
”
with a “
2
” in the part number.
Note the RTD wiring configuration diagrams shown on page 149.
The standard metal sheath for
RTD elements is 1/4” diameter made of 316 stainless steel. Inconel 600 sheaths can be specified by changing the “
16
” in the
part number to a “
09
”.
Example part number:
4E164-11-12-24
is a four wire, European curve, 316 Stainless Steel 1/4 inch
diameter sheath, 100
Ώ,
12” probe, 24” probe and leads overall.
Note:
Richards standard RTDs have a maximum service temperature rating of
400°C
(
752°F
). Our high temperature
RTDs have a maimum service temperature rating of
650°C
(
1202°F
). If you would like to specify this option, add a “
H
” after
the curve designation letter (
A
or
E
) in the catalog number.

4EH164-11-12-24
is a High Temperature
,
Four wire, European curve, 316 Stainless Steel 1/4 inch
diameter sheath, 100
Ώ,
12” probe, 24” probe and leads overall.
