Franklin Lakes, NJ — Digital electronics and precision engineering contribute to the small size of the latest addition to Process Sensor Corp’s IR thermometer line.
Process Sensor DS-40N Temperature Sensor
The DS-40N and DG-40N series of stainless steel pyrometers are 124.5mm long overall by M40×1.5 threaded diameter, operate in a current loop powered mode to produce a linear 4 to 20mA output over selected temperature ranges from an overall span of 250 to 2500°C in two models.
In a 4 wire mode, the sensor also offers green LED, illuminating the exact target size, or laser aiming.
Depending on the model, either DS-40N or DG-40N, and temperature range, selected optics provide small target, close focus e.g. 1.2mm diameter at 210mm distance, or extended focus out to 4m with a 20mm diameter target.
A USB connection gives access to PC adjustments of such parameters as emissivity, response time, temperature sub-range and peak picker, with supplied software.
These non-contact sensor will operate in ambient temperatures up to 70°C without cooling. Adding the optional cooling and lens-purging jacket can extend ambient temperatures higher to 200°C .
The Model DS-40N has a spectral response of 0.8 to 1.1µm, and the DG-40N 1.5µm to 1.8µm, for minimum vulnerability to variable target emissivity, and to optimize the effective emissivity of low radiance targets.
The temperature ranges, optics, rugged construction and signal processing capability will appeal to users in the Steel, Ceramics and Glass Industries, Cement and Refractory manufacture, Induction Heating and Sintering operations.
Process Sensor “PSC Spot Software” supports sensor set-up, multi-tasking, graphic display of temperature trends, and data logging, and in general allows the user to customize the sensor to the application.
Minco Chill-Out™ Combination Sensor

Minneapolis, MN — Minco has a new line of heating, ventilating and air conditioning (HVAC) temperature sensors designed to protect chillers in air handling equipment in commercial buildings. The new sensor line is called the Chill-Out™ Combination Sensor.
Visit Minco’s Total Cost of Ownership (TCO) Calculator to see your true savings if you install both a freeze stat low limit device and an averaging sensor.
Most schools, hospitals, office complexes and other commercial buildings use a device called a Freeze Stat, along with an averaging sensor to protect against freezing temperatures. The solid state, low temperature cut-out Chill-Out sensor has a number of advantages over traditional Freeze Stat/averaging sensor technology:
– Minco’s Chill-Out™ Combination Sensor replaces the Freeze Stat, but, unlike the Freeze Stat, it has two sensors in one easy-to-install package. One is a low-temp cut-out sensor and one is an independent averaging-temp sensor. This dual sensor package delivers accurate measurements and eliminates the need to install a separate averaging sensor.
– Saves $13K-$35K over a typical Freeze Stat/averaging sensor installation.
– There are no capillary tubes to break, leak or kink.
– Considered a “green” product by the industry as it is solid state and has no harmful gases or chemicals.
– Easy mounting in any direction. Horizontal orientation is not required.
– Relay changes state to deliver a failure detection signal in the event of a power loss.
– Low-temp sensitivity within a 12-inch segment, versus 18 inches with gas-filled capillary tubes.
– Easily formed aluminum or ultra flexible PVC coated galvanized armor sensor case.
– 4 to 20 mA temperature loop output available with optional Temptran™ transmitter.
– No diaphragm case needed.
The Chill-Out Sensor is described in the handy Sensors & Instruments Solutions Guide. The free 163-page guide explains various temp sensing solutions for process building automation and other commercial applications. The guide has complete technical data on sensor assemblies, probes, miniature sensors, sanitary sensors, stator RTDs, HVAC temperature and humidity sensors, flexible sensors, elements, instruments, transmitters and accessories. In addition to the Guide, a Non-Invasive Sensors Design Kit is also available.

Filed under Temperature
AutomationDirect’s ProSense line of process sensors now includes temperature switches, temperature transmitters and RTD temperature probes.
The TSD25 series switches offer dual output setpoints over an operating temperature range of -13 to 284°F. With 4-20mA analog outputs, the TTD25 series of transmitters provides a compact temperature monitoring system over temperature ranges from 0 to 100°C or 0 to 300°F. The four-wire, 100 ohm platinum RTD probes are made of durable 316 stainless steel and measure temperatures ranging from -40 to 302°F. The 10 mm diameter probes are available in lengths from 160 mm to 560 mm. Thermowells and fittings are also available.
Resistance Temperature Detector Sensors

St. Louis, MO – Watlow offers a full line of Resistance Temperature Detector (RTD) sensors for a wide variety of process and industrial applications. Watlow engineers can also solve difficult application problems and offer solutions tailored to meet specific application requirements.
Watlow’s RTD sensors are designed to ensure precise and repeatable measurements as well as meet environmental requirements for each application. A high signal-to-noise output increases the accuracy of data transmission and permits greater distances between the sensor and the measuring equipment. Watlow’s RTD sensors can be configured to meet specific application needs with options including element type, lead wire configuration, termination style, sheath materials, lengths and diameters, process connection heads, transmitters, thermowells, spring loading, flanges and surface mount packages.
Watlow RTDs offer a high degree of accuracy and a wide temperature operating range of -200 to 650°C (-328 to 1202°F). The linear change in resistance per degree change in temperature makes it easy to interpret the signal, allows for less complex instrumentation and requires no cold junction compensation like that found in a thermocouple.
Predictable resistance at a given temperature can be produced with Watlow’s RTDs. Resistance wire RTDs have a positive coefficient by increasing resistance with temperature increases. These sensors work in a variety of industries including processing, food equipment, plastics processing, petrochemical processing, microelectronics, and air, gas and liquid temperature measurement.
