Product Description
Schneider STP300-100 -50/50 Loop Thermo Transmitter
Part Number: 006920221
Product Code: STP300-100 -50/50
4-20mA 100mm Stem Two Wire Water Signal
Product Code: STP300-100 -50/50
4-20mA 100mm Stem Two Wire Water Signal
Product Overview
Measurement Precision: Every hydronic control loop depends on the accuracy of its sensing probe. The 006920221 is engineered as a precision measurement instrument, featuring a stainless-steel stem that installs through a separate closed pocket, allowing element replacement without draining the circuit.
Robust Construction: A sealed transition separates wet metal from cable connections, while the factory-fitted gland protects against condensation, dust, and wash-down spray. This passive device requires no firmware updates or battery replacements, drawing minimal current from the controller's measuring circuit.
Bipolar Range Advantage: Specifically designed for circuits that may drop below freezing, the bipolar temperature span prevents signal clipping at low temperatures, ensuring accurate monitoring throughout the entire operational range.
Each unit undergoes traceable temperature reference calibration before packaging, with documentation suitable for commissioning records, handover dossiers, and energy-audit evidence.

Application Scenarios
This transmitter variant is specifically engineered for demanding environments including:
- Cold-store pipework and refrigeration systems
- Ice-water loops and chilled water circuits
- Outdoor hydronic circuits and exposed piping
- Chilled accumulators during pull-down phases
The bipolar temperature range ensures measurement remains within the calibrated band during sub-zero conditions, enabling frost-protection systems to operate on accurate data rather than assumptions. The 4-20 mA signal protocol maintains integrity over long cable runs, making it ideal for installations where control panels are located at significant distances from monitored piping.
