HLS 310T Dual Output Level And Temperature Transmitter Features
Simultaneous Level And Temperature Measurement
The HLS 310T measures hydrostatic level and liquid temperature within one submersible instrument, supporting a simpler installation for applications requiring both values.Independent 4 To 20 mA Signal Circuits
Separate galvanically isolated two wire circuits transmit pressure and temperature values independently, enabling direct connection to compatible control and monitoring systems.Integrated Pt 100 Temperature Element
The integrated Pt 100 Class B element provides temperature accuracy of up to ±1°C, with compensation time dependent on the temperature and environmental conditions.Wide Hydrostatic Level Range Selection
Nominal level ranges from 0 to 1 mH₂O through to 0 to 250 mH₂O support shallow tanks, water treatment equipment, open water and deeper storage applications.Stable Pressure Measurement Performance
Standard pressure accuracy is up to ±0.5% of span below 0.4 bar and up to ±0.35% of span from 0.4 bar. An up to ±0.25% of span option is available from 0.4 bar.Low Thermal Effect And Long Term Stability
The probe has a compensated pressure range of 0°C to 70°C and long term pressure stability of up to ±0.1% of span per year at reference conditions.Stainless Steel Submersible Construction
A stainless steel 316L housing and diaphragm, removable POM C protection cap and IP68 protection provide robust performance in compatible submerged liquid environments.Configurable Cables, Seals And Drinking Water Option
PVC, PUR, FEP and TPE U cable options are available, alongside FKM and EPDM seals. Drinking water certification is available with the required EPDM seal and PUR cable configuration.
HLS 310T Applications For Level And Liquid Temperature Monitoring
The HLS 310T is suited to applications that require continuous measurement of both level and liquid temperature from one submerged sensor. Its separate analogue outputs and robust stainless steel construction make it appropriate for water infrastructure, treatment processes, storage tanks and compatible fuel or oil monitoring duties.
Suitable applications include:
Drinking water treatment systems with a compatible certified configuration
Water storage tanks
Water recycling facilities
Filtered sewage treatment processes
Rainwater overflow basins
River and open water monitoring
Pump stations and lift stations
Tank batteries
Industrial water process tanks
Cooling and process water monitoring
Fuel storage tanks
Tank farm level and temperature monitoring
