NOSHOK Robust Sensors

In crucial temperature requirement applications, temperature sensors must be durable enough to withstand extreme high and low temperature ranges while providing highly accurate and clear temperature or temperature gradient measurement.

NOSHOK’s 850 Series Electronic Indicating Temperature Switch/Transmitter utilizes PT100 technology to provide continuous temperature monitoring, electronic temperature switching, and transmission of analog output of 4-20 mA while providing local digital indication.

These sensors are cost-effective, easy to integrate, and play a critical role in the functionality and maintenance of many complex temperature-dependant systems. Temperature transmitters convert a low-level (ohm or mV) signal to a standard 4-20 mA current signal that can be easily read by a monitoring and control system, like a CDS or PLC.

Two buttons on top of the 850 allow simple adjustment of the temperature set points, reset points, switching functions and the measuring range of the optional analog output. Its convenient 330° rotatable display-head and 4-digit LED display allow easy reading in any location. This sensor also provides one of the widest measuring ranges available (between -200°C and 600°C) to cover the majority of temperature measuring and switching tasks.

A variety of stem lengths, which are also available with adjustable insertion lengths, add to the versatility of the NOSHOK 850 Series. All wetted parts, as well as its housing, are made of stainless steel for corrosion protection and durability.

There are a wide range of applications which can utilize this type of a transmitter/switch, including:

HVAC – The temperature switch monitors the heating and cooling circuit and with the pre-determined switch points keeps it operating at optimum efficiency.

Air Conditioning Technology – The temperature switch in this application of large commercial or industrial size A/C units can be used to monitor the heat on the motor and cool or shut it down when exceeds set point.

Environmental Technology – In this industrial composter, the temperature switch can monitor and sustain the temperature of above 131° F needed for sanitation, but also allow sufficient oxygen airflow for aerobic degradation without dropping below that temperature.

Industrial Automation & Power Generation – In this application, the engine’s coolant system can be monitored. When the temperature increases to the switch point, other motors turn on to reduce load on the original motor or take over.

Industrial Manufacturing – In this application there are a number of situations for which the switch can be used, such as monitoring boilers, coolers, machine and metal temperatures.

Marine – In this re-circulating aquatic system, the temperature switch maintains the crucial temperature for good water quality, as well as the health of the fish being raised for commercial consumption purposes.

Transportation – The temperature switch in this application monitors critical rail temperatures and alerts of any problems.
