E-HELP: Using the CPA to Create a Temperature Switch

E-HELP: Using the CPA to Create a Temperature Switch
Q: I am looking for a device to create a temperature switch. I currently use a simple temperature switch with a 230°F setting, but at times the temperature of the unit goes over 400°F briefly and destroys the switch. I need to be able to hook a thermocouple up to the device and program a setpoint (with no display required) and have a set of dry contacts open when the temperature rises above the setpoint.

TCS Handles Up to 32 Measurements...And More

TCS Handles Up to 32 Measurements...And More
Moore Industries’ TCS Temperature Concentrator System is an ideal solution for low-cost temperature measurements. At its heart is the 16-channel, loop-powered (2-wire) TCM Temperature Concentrator Module. When two TCM modules are used in a TCS, up to 32 signals can be monitored over one twisted wire pair. The TCM is approved for use in hazardous areas (Div 2/Zone 2 and Div 1/Zone 0/1) and can be used with an HMC (HART to MODBUS RTU Converter) when communication with a MODBUS RTU master is required.

E-HELP: Adjustable Deadband Thermocouple Alarms

E-HELP: Adjustable Deadband Thermocouple Alarms
Q: We currently are using TCA Thermocouple Alarm units in our plant (model TCA/K-10MV/SX1/117AC/[STD]). The user’s manual says that the deadband is fixed at 1% of the input range. However, we need the TCA to trip at a set point of 190°F and reset at 180°F. Is this model capable of meeting this requirement and do you still manufacture this model?

IPH2 Custom Output Ranges Help Copper Smelter Replace Instrumentation

IPH2 Custom Output Ranges Help Copper Smelter Replace Instrumentation
The IPH2 is an economical choice for converting current signal to a pneumatic signal to provide precise, proportional control of valves, actuators and other pneumatically-controlled devices. One of its key features is the wide range of input and output choices. It is available with 4-20mA or split range inputs and 22 standard direct and reverse output ranges. In addition, custom ranges are also available – a fact that helped the Belgian branch of a global copper group when upgrading their instrumentation.

E-HELP: 3-Wire Options with the WORM

E-HELP: 3-Wire Options with the WORM
Q: Does the WORM Flexible Sensor RTD have a 3-wire option? If not, can I eliminate the fourth wire by jumping two of the parallel wires together?
