German engineering history and ESD manufacturing standards at REISSMANN

German instrumentation manufacturer REISSMANN Sensortechnik was established in 1993 by engineer Hans-Joachim Reissmann in Schwäbisch Hall.

Over three decades the enterprise developed from a specialized technical workshop into a prominent designer of precision temperature sensors and drive control electronics.

Modern manufacturing facilities located in Rosengarten-Uttenhofen and Hamelin feature automated metering lines, resin potting stations, and robotic soldering systems.

The entire production and testing area is qualified as an electrostatic discharge protected zone in full compliance with the DIN EN 61340 standard. Conductive flooring systems and permanent personnel grounding eliminate electrostatic risks to sensitive semiconductor components during fabrication.

Operational principles of PTC Kaltleiter and NTC thermistors in motor protection

Thermal protection for motor windings relies on miniature positive temperature coefficient PTC Kaltleiter thermistors developed by REISSMANN.

Upon reaching the rated trigger temperature threshold, the electrical resistance of the ceramic element surges by multiple orders of magnitude, providing an instantaneous digital input signal for protective trip relays in the power circuit.

In drive assemblies requiring continuous thermal measurement, negative temperature coefficient NTC thermistors are deployed.

Their resistance decreases predictably along an exponential curve as temperatures rise, allowing electronic controllers to monitor thermal trends within bearing shields and power conduits under variable duty cycles.

Installation characteristics of Nutenwiderstandsthermometer slot RTDs

REISSMANN slot resistance thermometers (Nutenwiderstandsthermometer) are engineered for installation within stator slots of high-voltage generators, wind turbines, and traction motors.

An ultra-thin flat profile starting at 1.5 mm allows insertion between insulated conductor bars without compromising slot fill ratios or risking mechanical puncture to surrounding winding insulation.

The detectors utilize platinum Pt100 and Pt1000 sensors compliant with international IEC accuracy classes.

Encapsulated in high-temperature glass-fiber laminate or polyimide film, they endure temperatures up to plus 200 degrees Celsius and withstand aggressive resin penetration during stator vacuum pressure impregnation cycles.

Signal conditioning architecture of Pt-Konverter and KTY-Konverter modules

To transmit temperature signals across industrial plants to central PLCs, REISSMANN manufactures dedicated electronic signal converters.

Pt-Konverter Micro transmitters mount directly inside the motor terminal enclosure, eliminating lead wire resistance errors and protecting low-voltage measurements from high-frequency interference generated by variable frequency drives.

The converter lineup includes SUB modules and DIN rail modules transforming resistance readings from Pt100, Pt500, Pt1000, and silicon KTY sensors into standard 4..20 mA or 0..10 V analog signals.

Hermetically sealed IP68 field enclosures ensure long-term stability in outdoor and washdown industrial environments.

Motor thermal monitoring with TMS-Basic relays and brake rectifiers

TMS-Basic and TMS-PTC-LB electronic monitoring relays deliver dedicated overtemperature protection using signals from embedded PTC thermistor loops.

The units detect resistance thresholds, rapidly opening control circuits during overload while continuously evaluating measuring loops for short circuits or wire breaks to prevent unmonitored equipment running.

Bremsgleichrichter brake rectifiers provide high-speed actuation for electromagnetic DC brakes in cranes, hoists, and conveyor drives.

Electronic overexcitation circuits supply a temporary voltage boost during release before switching to reduced holding voltage, limiting coil heating and speeding up brake engagement during emergency stops.

Condensation prevention in electric drives using Stillstandsheizung band heaters

During equipment downtime on outdoor conveyors, pump stations, and industrial fans, ambient temperature drops lead to moisture condensation inside motor enclosures.

To safeguard winding insulation integrity, REISSMANN supplies flexible Stillstandsheizung band heaters installed directly around stator end turns or internal housing surfaces.

A uniform surface thermal output keeps internal temperatures slightly above the ambient dew point, preventing liquid condensation and metal corrosion. The heaters incorporate heat-resistant silicone insulation and durable lead connections for seamless integration into motor control circuits.
