80GHz Radar Level Sensors: Siemens LR110/LR120 Alternative

For measurement sites such as wastewater facilities and small-size storage tanks, 80 GHz radar level sensors are widely adopted. Their narrow beam angle, short blind zone, plus good resistance against dust and lens condensation make them well-suited for these locations. This project calls for forty units of 80 GHz radar level transmitters as drop-in alternatives to Siemens LR110 / LR120, with a firm requirement for IP68 ingress protection. Off-the-shelf radar level sensors on the market typically top out at IP67, which cannot withstand submerged conditions. Only purpose-built radar level trans......

What Is a Pressure Snubber?

What Is a Pressure Snubber? A pressure snubber, also known as a pressure buffer, is a device designed to prevent intense fluid pulses and protect pressure instruments from damage. It is suitable for pressure systems where the medium being measured experiences pressure spikes, intense pulses, and rapid fluctuations. It is often used in conjunction with pressure gauges, pressure sensors, and pressure transmitters. Sino-Inst pressure sensors and hydraulic sensors can be configured with damping structures as needed, making them suitable for applications prone to pressure surges, such as hydraulic ......

Flush Diaphragm Pressure Transducers for Viscous, Slurry and Sanitary Media

Flush Diaphragm Pressure Transducers are specifically designed for measuring the pressure of viscous, low-flow, or hygienically sensitive media. They utilize diaphragm isolation technology and a no-bore design to prevent media blockages and leakage of the measured medium. Sino-Inst offers pressure transducers with flush diaphragms, flush-mounted diaphragms, and sanitary clamp-on flush diaphragms, among others. We also provide specialized Flush Diaphragm Pressure Transducers for high-temperature melts, earth pressure, and shield machines. RFQ Table of ContentsCan 80GHz Radar Replace Siemens LR1......

PT100 Resistance Chart

PT100 temperature sensors are commonly used platinum resistance sensors in industrial applications within the range of -200°C to 850°C. They measure temperature from the change in platinum resistance, which rises with temperature along the curve defined in IEC 60751. Here, “PT” stands for platinum, and “100” indicates a standard resistance value of 100 Ω at 0°C. Compared to other temperature sensors (such as thermocouples and NTC thermistors), the PT100 offers high accuracy (Class A: ±0.35 °C at 100 °C), excellent stability, and a nearly linear output. It is widely used in medical equipment, i......

How to Measure Viscosity: Step-by-Step Guide

How to Measure Viscosity? Simply put, it involves controlling the temperature, allowing the liquid to flow or undergo shearing, recording the time, torque, or vibration damping, and then converting these values into viscosity units such as mPa·s or cSt. There are many methods for measuring viscosity. For example, the capillary method can be used for oils; the rotational method for coatings or pastes; and online vibrating viscometers for process pipelines or reactors. If you do not have a viscosity measuring instrument, you can try the falling-ball method. RFQ Table of ContentsCan 80GHz Radar R......

IBC Tote Level Sensors and Alarms-Best Solutions

IBC totes are intermediate bulk containers for the storage and transportation of liquids, typically with capacities of 1,000–1,250 L (275–330 US gal). They are widely used in the chemical, coatings, food, and pharmaceutical industries. IBC totes are primarily classified by material into three categories: high-density polyethylene (HDPE), carbon steel, and stainless steel. Since the liquid column in an IBC tote is only about 1 m high, selecting the appropriate IBC tote level sensors and alarms can be a challenge for users. When selecting a sensor, the focus should be on the dead zone, not the m......

RTD Wiring: 2-Wire vs 3-Wire vs 4-Wire PT100 Diagrams

There are three options for resistance temperature detector (RTD) wiring: 2-wire, 3-wire, and 4-wire. The key difference lies in whether the measurement error caused by lead resistance can be eliminated. Simply put: 2-wire systems have large errors and are largely obsolete; 3-wire systems are commonly used in industry; and 4-wire systems offer laboratory-grade precision. Why are there these differences in wiring? A PT100 has a resistance of 100 Ω at 0°C, and its resistance changes by approximately +0.385 Ω/°C as the temperature changes (IEC 751 standard). The connecting wires themselves also h......
