Tek-Trol 7800A-0L1 – NEMA 4X Loop-Powered Process & Level Indicator with bar graph

Erik Prayoga — Mon, 22 Jun 2026 06:35:30 +0000

Tek-Trol 7800A-0L1 – Tek-LCD 7800A NEMA 4X Loop-Powered Process and Level Indicator is one of Tek-Trol’s most advanced and feature-packed plastic, field-mounted, loop-powered indicators. The fact that this meter is loop-powered means that there is no need to run additional, costly power lines. The Tek-LCD 7800A is built in a NEMA 4X and IP65 rated plastic enclosure which can stand up to even the harshest environmental conditions. It features a dual-line display that can be easily scaled in the field for any 4-20 mA analog input. The display has a five digit upper display, a seven alpha-numeric character lower display, and comes with a backlight standard. Two features that really make the Tek-LCD 7800A stand out are its wide viewing angle display and SafeTouch® through-window buttons. These buttons allow the meter to be programmed and operated through the cover window, thus eliminating the need to remove the cover in dirty or wet environments.

Tek-Trol 7900A-6H2 – Tek-Batch 7900A Batch Controller

Erik Prayoga — Mon, 22 Jun 2026 06:35:25 +0000

Tek-Trol 7900A-6H2 – The Tek-Batch 7900A is an analog input (4-20 mA, 0-5 V, 1-5 V, etc.) digital batch controller specifically designed for single and multi-stage batching applications. It provides excellent but simple batch control capabilities with features such as preclose relays and automatic overrun correction for more accurate batches and convenient SafeTouch® through-glass buttons for simple operation and menu navigation without having to remove the cover. The preclose deactivates a specific relay before the batch is finished in order to allow slower fill rates and increased accuracy. Automatic overrun correction keeps the batch size accurate over time and with system wear. The Tek-Batch 7900A includes a 24 VDC power supply to drive the flow meter and can be equipped with up to four internal relays and a 4-20 mA analog output.
