RdF‘s Heavy Duty Industrial Thermocouple Model 26881 is designed to surface mount in areas where the sensor itself may be subjected to harsh conditions.

The Model 26881 may be bolted or clamped into place on a flat mounting surface, or a surface with a specific radius. The AWG #20 stranded thermocouple lead wires are insulated with fiberglass insulation capable of withstanding temperatures to 480°C (900°F).

Temperature Range/Stranded Leads Limit
Type J:         0°C to 720/320°C ( 32°F to 1330/600°F)
Type K: –200°C to 760/480°C (–320°F to 1400/900°F)
Type T: –200°C to 370/200°C (–320°F to  700/400°F)
Type E: –200°C to 760/370°C (–320°F to 1400/700°F)

Thermocouple Types
“J” (Iron/Constantan)
“K” (Chromel/Alumel)
“T” (Copper/Constantan)
“E” (Chromel/Constantan)

Accuracy
Per standard limits of error
as stated in ASTM E230.

Insulation Resistance
The insulation resistance between the housing and the leads is
50 megohms with 50 Volts DC applied to a dry sensor
at room temperature.

Lead Wire
#20 AWG stranded thermocouple conductors,
fiberglass insulated over each and overall.

Mounting
Sensors can be bolted, clamped,
or welded into place.
