UltraTEV Detector
-
The UltraTEV Detector is the ideal instrument for initial PD surveys. EA Technology's UltraTEV Detector identifies faults BEFORE they lead to failures by testing for critical PD activity using both internal and surface sensors. This device is essential to personal safety and due to its self-explanatory LED display system requires minimal training.

40Gb/s Coherent Receiver
-
The integrated 40-Gb/s DP-QPSK receiver incorporates two 90° optical hybrids with four pairs of balanced photodetector (PD) and four linear TIAs into a single butterfly package. Unlike other technologies in which the polarization beam splitter (PBS) and/or the power splitter (BS) are not included, Optoplex’s receiver includes both of them with the optical hybrids, PDs and the TIAs to offer a fully integrated solution which will benefit users in terms of completely removing fiber routing and the skew management. The integrated receivers work at the symbol rate up to 12.8GBaud/s.

PocketDetect LRM
PD-01LM
-
Hachmann Innovative Elektronik
With a PocketDetect LRM you have a highly specialized, miniaturized and easy-going voltage detector at your fingertips. A thorough self-test ensures reliable function. A permanently enabled interface-tester warns against defect interfaces or residual voltages, while the low-power long-term display mode secures live working. The PocketDetect can be carried along due to its diminutive dimensions and lightweight (e.g. in the optional available belt case).

Positive Displacement (PD) Meters
-
Positive Displacement (PD) flow meters are volumetric flow measurement instruments ideal for low flow rates, highly viscous fluids, and measurement of flows involving starts and stops or pulsing. Positive displacement flow meters are similar in design to the gear pump. The principle of operation is reversed however; instead of the gears driving the fluid, the fluid drives the gears. A non-intrusive hall-effect sensor detects the movement of the gear and as each gear tooth passes the sensor, a square wave pulse is produced and a discrete volume of liquid is measured. The resulting pulse train is proportional to the actual flow rate and provides a highly accurate representation of the fluid flow.

Online Partial Discharge Monitor
ASM-E
-
The ASM-E is a permanent partial discharge monitor for cables, switchgear and other high voltage assets.The ASM-E can be configured with up to 128 PD sensor channels. If excessive discharge is detected, the ASM-E raises an alarm that can be configured either locally or by email/SMS. This enables the long-term assessment of plant conditions to be carried out quickly and easily, from any remote computer.

Partial discharge measurement with remote wireless reading
PD-LT
-
The PD-LT allows online partial discharge detection on cable accessories such as cable head for safety and maintenance purposes.The PD-LT indicates the intensity of the partial discharges, converting the electrical charge units (pC) into decibels (dB). Thus the reading is kept as a simple intensity level indication, proportional to the probability of a fault's presence in the tested medium voltage accessory.The remote display gives a dB value of the probe's measurement. The dB value will vary along with the discharges indicators on the PD-LT probe. The measurement range is from 0 to 65dB and the display will show ''OL'' if the reading is over 65dB.
