The Wacker Neuson Temperature Sender is a genuine OEM component designed for the HSH700 and HSH650 hydronic surface heaters. Sourced directly from Wacker Neuson, this part carries the same specifications as the original unit installed at the factory. It is confirmed to fit the HSH700 and HSH650 series, making it a straightforward replacement when the existing sender fails or reads incorrectly. Keep part number on hand for planned maintenance or unscheduled repairs to avoid extended downtime on heated concrete curing or ground thawing operations.
Key Features
- Accurate Temperature Signal Output — Genuine OEM construction ensures the sender delivers the correct resistance-to-temperature curve that the HSH control system expects, preventing false readings or erratic heater behavior.
- Direct Plug-In Replacement — Matches the original connector, thread pitch, and probe dimensions of the factory-installed unit for a clean installation without adapters or modifications.
- Confirmed Fitment for HSH700 and HSH650 — Verified for both the HSH700 and HSH650 hydronic surface heater models, covering the most common configurations in the Wacker Neuson HSH lineup.
- Protects the Heating System from Thermal Faults — A correctly functioning temperature sender allows the heater's control circuit to regulate fluid temperature within safe limits, guarding against overheating and nuisance shutdowns.
- Critical for Fuel and Control System Safety — In hydronic heaters, an inaccurate or failed temperature sender can cause the burner to run beyond safe thermal thresholds; using the correct OEM sender keeps the control loop operating as designed.
The temperature sender monitors the fluid temperature within the hydronic heating circuit and relays that information to the machine's control system as an electrical signal, typically a variable resistance. The control unit uses this reading to regulate burner output and maintain consistent fluid temperature throughout the heating loop. When the sender fails or drifts out of calibration, the controller receives incorrect data — resulting in overheating, premature shutdown, or a heater that won't reach operating temperature — all of which directly impact concrete curing schedules or ground thaw timelines on the jobsite.
