Tel-Tru Manufacturing microprocessor transmitters have sensors that are designed to maximize accuracy and durability. The fully integrated transmitters eliminate the chance of wiring disconnections between the transmitter and sensor, and increase the reliability over traditional RTDs that use transmitters with connection head housing. The standard assembly integrates a proven thin film PT100 platinum RTD sensing element with the transmitter electronics, packaging them both in an all welded 316 L stainless steel probe and housing assembly. Probes are available in .187 inch and .250 inch diameters with a choice of lengths ranging up to 12 inches. Overall range capability is –103 to 392°F, and ranges can be scaled in the field or at the factory to all common requirements.
