, based on technical specifications and operating procedures.
: Connects to most standard strain-gauge load cells (typically 4-wire or 6-wire).
The TPL-400 serves as a versatile interface for most standard load cells, converting weight signals into actionable digital data or analog outputs for process control. It is commonly used in tank weighing, hopper scales, and general force measurement systems. Key Features & Functions Calibration & Scaling
The TPL400 is typically housed in a rugged enclosure, often rated (dust-tight and protected against water jets), making it suitable for harsh environments where dust and moisture are prevalent. The front panel usually features a membrane keypad for durability and a high-contrast LCD display capable of showing weight data, status indicators (Zero, Tare, Gross/Net), and programmable text.
Shielding: Connect the cable shield firmly to the designated functional earth/ground terminal on the instrument to eliminate electromagnetic interference (EMI). 3. Configuration and Calibration Procedures lahti precision tpl400 manual
The device balances high resolution with rugged field protection. Refer to the data sheet for core hardware operational boundaries: Up to 0.05% of full scale.
The unit is designed for panel mounting. When cutting the panel aperture:
: For official paper copies or specific legacy handbooks, you can check the Lahti Manuals section on ManualLib or contact Lahti Glass Technology (formerly part of Raute/Lahti Precision). Key Specifications from the Manual Accuracy Class : 0.05 with an internal resolution of 130,000. Analog Outputs : Galvanically isolated 4–20 mA and 0–10 V. Calibration
Supports 4-wire or 6-wire load cell connections and can drive up to ten 350 Ω load cells. , based on technical specifications and operating procedures
Lahti Precision equipment is durable, but finding documentation for older, specialized equipment can sometimes be a challenge. To find the manual:
: You can manually adjust the scaling of analog outputs to match the weight range of your specific application.
: Some units may include relay modules for setpoint control (e.g., triggering an alarm when a specific weight is reached). 3. Operation and Maintenance
Operating temperature range of -10 to +50 °C. Enclosure Options: Standard: IP65 ABS plastic. Variants: Stainless steel (TPL-400S), Die-cast ( ), or DIN-rail ( 2. Installation and Wiring It is commonly used in tank weighing, hopper
Can be activated via external contact closure to reset the weight to zero.
: Mechanical mounting and electrical wiring for load cell inputs and power. Programming : Navigating the menu system to set control parameters. Calibration
If the indicator fails to read weight accurately but shows no error codes, perform an electronic health check:
: Includes auto-tare, peak hold (activated via external contacts), preact values, and hysteresis settings. Manual & Documentation Resources
Captures and displays the maximum impact force recorded during a cycle. This can be tripped remotely via an external volt-free contact closure.
