About this manual

The TPL-300 is a digital load cell amplifier designed for field installation in silo and tank weighing and level monitoring. It works with all types of strain‑gauge load cells and offers features such as auto‑tare, peak hold, and set‑point relays.

The manual covers calibration using the built‑in programmer or an external device, describes the analog (4–20 mA, 0–10 V) and serial (RS‑232/RS‑485) outputs, outlines environmental limits, power requirements, and mechanical construction options (plastic, die‑cast, stainless steel, IP65).

Frequently asked questions

How is the TPL-300 calibrated?

Calibration is performed at two points (e.g., 0 and max) by entering the loading data into the device’s memory using the built‑in programmer or an external programming device.

What output options does the TPL-300 provide?

It offers galvanically isolated analog outputs of 4–20 mA and 0–10 V, as well as serial communication via RS‑232 and RS‑485 with selectable baud rates.

What is the protection class of the TPL-300 enclosure?

All TPL-300 variants have an IP65 protection class.
