ZMJ100XDR

* Employs gas compensation for enhanced setpoint accuracy * Offers Class 1 accuracy across the full measurement range, with higher precision in remote transmission modules and improved consistency between local display readings and remote data. * Features a dual-compensation system to ensure more accurate actuation of the meter's indicator‑box contacts across the entire temperature range. * Suitable for diverse indoor and outdoor installation requirements. * Equipped with microswitches that allow seamless switching between normally open and normally closed states. * Supports up to three pairs of contacts, enabling multiple configurations such as dual alarms and dual interlocks for safer, more reliable monitoring. * Includes an RS485 bus interface for easy system expansion and remote operation. * Highly vibration‑resistant, requires no oil filling, and is leak‑free.

TR-80-R

The device features triple alarms and triple interlocks, along with a three‑level redundancy design, enhancing product reliability. It enables real-time online monitoring of gas volume and transmits data to the backend via an RS485 digital signal (compatible with a 4–20 mA analog signal). An external, standalone gas‑volume monitoring chamber isolates the measurement from interference caused by the operation of other components. The all‑metal, high‑strength mechanical structure ensures stable performance even at flow rates as high as 2.5 m/s. The float's main pivot is fitted with imported precision bearings, providing enhanced support and eliminating potential wear‑related issues in the float shaft bore. A streamlined float design maintains stable orientation even under high‑velocity oil flows.

Digital Leakage Current Meter for Surge Arresters

It employs a high-precision through‑core current transformer that is fully isolated from the primary circuit, ensuring high safety; it adopts a distributed measurement architecture—local measurement with digital transmission—using RS‑485 digital signals to the backend system; it offers superior measurement accuracy, exceeding national standards; its integrated structural design features three‑layer shielding for enhanced reliability; it utilizes an LED display to present monitoring data, facilitating easy observation; and its ingress protection rating reaches IP66.
