The Temperature Transmitters Series for Putzmeister® concrete pumps offers a robust range of industrial-grade sensors engineered to monitor the temperature of hydraulic oil, engine coolant, exhaust gases, and key mechanical components. These sensors deliver critical data to the control system, enabling intelligent thermal regulation, preventing overheating, and safeguarding the pump's performance and longevity—whether operating in Burnaby or on construction sites worldwide.
🔧 Key Features & Benefits
Accurate Temperature Sensing Provides highly precise temperature readings essential for real-time monitoring and decision-making by the control system.
Intelligent Signal Output Converts temperature readings into standard electrical signals (voltage or current) for seamless integration into the pump’s electronic control unit (ECU).
Thermal Protection Logic Enables automatic responses to high-temperature conditions—such as activating a hydraulic cooler or triggering a shutdown alert to prevent catastrophic failure.
Optimized Performance Helps maintain components within optimal thermal ranges, ensuring efficient pump operation and fluid performance (especially for hydraulic oil).
Heavy-Duty Construction Built to endure harsh concrete pumping environments—resistant to vibration, fluid exposure, and extreme temperatures.
Versatile Options Available in multiple sensor technologies (thermistors, RTDs, thermocouples), thread sizes (including M14x1.5), and preset switching points (like 55°C) to suit a variety of system needs.
Plug-and-Play Compatibility Designed specifically for Putzmeister® control systems—ensuring easy installation and full system compatibility.
🔍 Component Overview (Based on Images)
Brass Temperature Transmitter (Large Left Image): A common model featuring a threaded M14x1.5 connection and likely a preset switching point of 55°C. This sensor is used to monitor hydraulic oil or coolant temperatures and initiate a response when thresholds are exceeded.
Additional Temperature Sensor Variants (Right Images): Include models with different probe lengths, body materials, and electrical terminal types. These may be designed for use in:
Hydraulic circuits
Engine cooling systems
Ambient air monitoring
Surface or immersion sensing
Some are designed for screw-in applications (into a port or housing), while others are clamp-on or external surface sensors.
🏗️ Application within Putzmeister® Concrete Pumps
These sensors serve as thermal sentinels across multiple systems:
🔍 Monitoring Target
⚙️ Function of Transmitter
Hydraulic Oil
Triggers coolers or shutdown warnings if oil exceeds 55°C (or other setpoint)
Engine Coolant
Maintains proper combustion temps and prevents engine overheating
Exhaust Gas
Detects anomalies and optimizes fuel-air mix in advanced models
Bearing Assemblies
Prevents failure by tracking excessive heat in high-friction areas
Ambient Environment
Informs system adjustments or displays for operator awareness
✅ Why Temperature Monitoring Matters for Concrete Pumping
🚫 Avoids Costly Downtime Prevents damage to critical systems like the hydraulic pump or engine, reducing service costs.
⚙️ Ensures Consistent Operation Keeps system fluids within safe temperature ranges, avoiding performance dips.
🔒 Protects Your Investment Extends the life of expensive components by alerting operators to thermal stress early.
🔥 Enhances On-Site Safety Prevents hazardous overheating conditions, contributing to overall job site safety.
📘 Compatibility & Part Selection Guidance
When choosing the right temperature transmitter, especially for replacements or upgrades in models like the Putzmeister® BSF, MXR, or TK series, always verify:
✅ Thread type and size (e.g., M14x1.5)
✅ Electrical output (voltage, resistance, or current)
✅ Temperature range or fixed switching point (e.g., 55°C)
