Product Description
VTH temperature and humidity transmitters are suitable for use in many application areas. They can be used safely in many fields, from cold storage rooms and poultry farming to office temperature-humidity monitoring systems and isolated rooms. They stand out from similar products in measurement accuracy and product quality. * Precision temperature and humidity sensor of American origin * 14 mm high display showing instantaneous temperature and humidity values, readable from 15 metres * 2 different analog outputs for temperature and humidity (4-20 mA or 0-10 V) or 2 x 3 A relays (for control or alarm purposes) * RS485 Modbus communication on the relay-output module * IP65 protection, optional IP68 protection * 24 VDC supply * Wall mounting, line mounting or threaded mounting options * With the optional 2 sensor inputs, the temperature-humidity values or averages of 2 different zones can be monitored in a single device * Inverter control directly via analog output without needing a second device * Sensor can be extended up to 30 metres * Stainless steel, brass-filtered, threaded stainless steel and PVC sensor housing options
