TRP SENSOR
The iWorx® TRP Series are thermistor type 10K Ohms (Type III) sensors. They provide temperature input information
to a controller such as the ZXU or BLMC.
The thermistor’s higher resistance creates a larger signal with the same measuring current, negating most lead wire
resistance problems and eliminating the need for signal conditioners.
Overview
The TRP Series offers a stainless steel bullet probe which is 1/4” in diameter and 1” long. It is available in two varia-
tions of lead length:
The TRP Series can measure the boiler supply and return water temperature or the outdoor temperature (provided it is
mounted in a weatherproof enclosure) or the temperature atop a concrete slab and provide this information to the con-
trollers.
Features
• Directly connects to selected iWorx® controllers via low-cost, shielded, twisted-pair cable.
• Stainless steel probe.
• Output: 10K Ohm @ 77º F.
