Schneider STP300-200 Immersion Temperature Transmitter
Part Number: 006920301 Probe Length: 200mm Temperature Range: 0-100°C Output Signal: 4-20mA
Product Overview
The STP300-200 is a two-wire immersion temperature transmitter designed for hydronic pipework applications.
It converts water temperature inside pipes into a linear 4-20mA signal that building controllers can read
on standard analogue inputs. The 200mm stem length ensures the sensing tip reaches moving water through
insulation, providing accurate fluid temperature measurement rather than cladding temperature.
With a measurement span of 0-100°C, this transmitter concentrates the current signal precisely within
the operational range of heating and chilled water circuits, maintaining high resolution where needed.
The ±0.4% accuracy ensures reliable performance for supply and return temperature control applications.

Installation & Integration
Proper installation begins with selecting an appropriate thermowell pocket that positions the sensing tip
in the flow stream rather than stagnant areas. Installation should occur where water is well-mixed and
moving, away from valves and bends.
Important Considerations:
• Total loop resistance must account for controller input plus cable resistance
• Verify loop resistance limits for long cable runs
• Record zero and span during commissioning against reference standards
• Monitor supply and return temperature trends for system diagnostics
Application Scenarios
Heating and Chilled Water Systems: Control loops, energy accounting, and performance reporting
District Heating Interface Units: Primary side temperature measurement for consumption allocation
Chiller and Boiler Sequencing: Accurate supply/return readings for plant staging decisions
Thermal Stores and Buffer Vessels: Penetration through insulation and stratification layers
Commissioning Reference: Temporary verification tool for permanent installation validation
