Product Description
TA3405 is designed for reliable temperature measurement on mobile working machines and demanding industrial equipment. Its Pt1000 Class A element provides accurate measurement across the specified temperature range. The 30 mm insertion length provides a compact sensing point for machine installations. The 4–20 mA output provides straightforward integration with machine controllers. Its robust mechanical design supports high-pressure, vibration-intensive and outdoor environments.
Measurement Performance
The transmitter measures temperature through a Pt1000 Class A sensing element. Internal electronics process the resistance signal and generate a proportional 4–20 mA output. The analogue resolution is specified at 0.04 K. The T05/T09 response times are approximately 1 and 3 seconds. This fast response supports dynamic mobile-machine temperature monitoring.
Rugged Construction
TA3405 features a stainless-steel 316L housing and wetted construction. The G 1/2 external thread provides secure process installation. The device is rated for pressure resistance up to 400 bar. IP68 and IP69K protection supports demanding environmental conditions. Shock resistance up to 50 g and vibration resistance up to 20 g make it suitable for mobile machinery.
Electrical Integration
The transmitter operates from 10–30 V DC. Its M12 connector uses gold-plated contacts for reliable electrical connection. The analogue output delivers 4–20 mA with a maximum load dependent on supply voltage. Reverse-polarity, short-circuit and overload protection improve system reliability. The transmitter can be integrated directly into PLC and mobile-machine controller architectures.
