OEM RTD Capsules
RdF develops low cost RTD capsules with benchmark specifications such as ultra-fast response and wet immersion capability to fit into standard holes or to bond on to small surfaces. Contact our application engineers to customize capsule size and leads to ‘exact fit’ at lowest cost.

Insertion Capsules

Sealed Metal Capsule RTDs
Proprietary process directly seals the element and lead attachment for wet applications and fills for fast response. These strong, ready for use 2" long stainless steel capsules also function as probes. (For aggressive chemicals see Immersible Capsules)

29258 –	0.250" + 0.004" – 0.000" diameter stainless, immersible
29259 –	0.187" + 0.004" – 0.000" diameter stainless, immersible
29260 –	0.125" + 0.003" – 0.000" diameter stainless, immersible

Micro-Capsule RTDs
The smallest diameter 0.6" long stainless steel or ceramic capsules are precision sizes. Each is offered moisture resistant or in high temperature ranges.

29348 –	<0.066" diameter stainless, moisture resistant
29362 –	<0.066" diameter stainless, max temperature
29363 –	<0.086" diameter alumina, moisture resistant
29326 –	<0.086" diameter alumina, high temperature
	(also under Non-Metal Capsule RTDs)
29364 –	<0.086" diameter alumina, max temperature

Non Metal Capsule RTDs
0.6" long capsules fit standard holes or tubes; in every temperature range. RdF’s exclusive, rugged designs in precise diameters include choice of 2, 3 or 4 wire lead configuration.
