SDI-12 8-Channel PT100/PT1000 Interface TBSPT8-DR

The TBSPT8-DR is a precision 8 – channel PT100/PT1000 interface. Measurement and configuration is controlled via SDI-12 commands. The interface is equipped with 4-wire inputs, matched noise filters, surge- and over voltage protection.To achieve high precision, the TBSPT8-DR is calibrated to an absolute accuracy of ±0.02°C at 0°C, using a ±0.005%, ± 2ppm/°C  resistance standard. The device has a resolution of 0,001°C and a temperature drift less than ±0,01°C over the temperature range -40°C to + 80°C.  Noise is ±0,0015°C when used with PT1000 sensors and ±0,01°C when used with PT100 sensors.The device can output the measurement results in °Celsius or °Fahrenheit.Specifications Precision, 4-wire PT100/PT1000 interface 8 measurement channels Resolution: 0.001°C Noise: ± 0.0015°C (PT1000) Absolute accuracy at 0°C: ± 0.02°C Measurement range: -80°C to +300°C Temperature drift: < ± 0.01°C Configurable measurement units: °C, °Fahrenheit Surge- and over voltage protection SDI - 12 standard
