MTP-NT telemetry is a small and flexible telemetry system that has a modular design. It consists of freely selectable sensor modules, a controller module and an inductive transmitter unit. Depending on the needs of the user, the telemetry system can be freely assembled and subsequently adapted.

• channels: 2 - 128
• signal bandwidth: 0 – 24 kHz
• input types: strain gauge, TH-K, PT100, PT1000, IEPE, voltage
• resolution: 16 bit
• transmission: inductive or radio
• power supply: inductive or battery etc.
• housing: robust and water resistant
• operating temperature: -40 … +85 (125) °C
• module dimensions: approx. 60 x 40 x 10mm, approx. 60 x 40 x 20mm, depending on the design

MTP-NT telemetry offers two module types for sensors: a universal analog module for voltage, strain gauge (quarter-, half- and full-bridge) and IEPE sensors and a temperature module for measuring thermocouples (Type K and Type J) and PT100/1000. Each sensor module is available in a 2-channel or 4-channel version and is equipped with signal conditioning, antialiasing filters, A/D converters and a digital output.

Up to 64 modules (128 channels) can be controlled with a single MTP-NT controller module. The modules can be placed close to the sensors and connected to each other over longer distances of up to 10 m via interference-free digital outputs. This avoids unwanted noise. The output of the MTP-NT controller is a bit-serial PCM signal that is modulated for wireless transmission and can be transmitted inductively over distances up to 50 mm. It is designed for data rates up to 10 Mbit/s.

For permanent installations, e.g., in test benches or production facilities, telemetry often has to work uninterrupted for days or weeks. For this purpose, the MTP telemetry uses a non-contact, inductive power supply. Using a stationary inductive head and a receiver coil on the rotating component, the supply voltage for telemetry is transmitted without contact.

Depending on the application, different non-contact transmission links are available, e.g., an inductive coil antenna for distances up to 50 mm and a transmission rate of up to 10 Mbit/s. This allows, for instance, for 32 parallel channels, a signal bandwidth of up to 6,000 Hz and a corresponding 24,000 Hz with eight channels.
