S70-TP Lascar

S70-TP Four-Channel Thermistor Board for 7 PanelPilotACE Display S70-TP is a four-channel thermistor board to add temperature measurement functionality to the SGD 70-A PanelPilotACE display. Within the PanelPilotACE Design Studio software users can choose to display, log or graph the temperature inputs. SGD 70-A display sold separately The S70-TP is an accessory to the PanelPilotACE range of compatible displays and panel meters and is compatible with the 7 PanelPilotACE display module (SGD 70-A). The S70-TP mounts on the rear of the SGD 70-A and provides up to four thermistor inputs which can then be utilised within the free PanelPilotACE Design Studio software to measure, display, log and graph temperature readings. The S70-TP is designed to work seamlessly with Lascar Electronics EasyLog thermistor probes which are available in a variety of lengths and accuracy specifications as well as bottle formats for use in vaccine monitoring applications. Other thermistor types can be used by adjusting the calculation values in the Design Studio software. Each S70-TP is supplied with a 1m thermistor probe fitted with a 3.5mm jack plug and featuring a potted metal sheath (Lascar part number: EL-PROBE2-1.0M-TP). Specifications Supplied probe measurement range -40C to +80C (-40F to +176F) Thermistor resistance 4k7 to 22k NTC Internal Resolution 0.01C (0.01F) Temperature Accuracy 1.0C (2.0F)* Number of Channels up to 4 Outside Dimensions 70 (2.7) x 38 (1.49) x 20 (0.78) mm (in) * Between -5C and 40C without offset calibration. Between -40C and +80C with offset calibration applied. www.panelpilot.com electronics Issue 1 08/2016 N.R. Page 1 of 2S70-TP Four-Channel Thermistor Board for 7 PanelPilotACE Display Dimensions and Mounting All dimensions are in mm (in) 19.25mm 70mm The diagram (above-right) indicates the pins on the SGD 70-A that the S70-TP should be connected to. Compatible Thermistors The Thermistor Element in the Design Studio uses the Steinhart-Hart formula to convert the voltage reading generated from the thermistor add-on board into a temperature reading. The Element can work with either positive temperature coefficient (PTC) or negative temperature coefficient (NTC) resistive sensors. For best results, choose a thermistor which has its resistance approximately equal to the bias resistor value of 10k in the middle of the temperature range you want to monitor. You will also need the resistance table for the chosen thermistor. It is possible to change the 10k bias resistor for another value if you wish. Operating Mode Up to four thermistors can be connected to the S70-TP at any time, with each thermistor input channel using the corresponding analogue input channel of the SGD 70-A (for example Thermistor 1 uses Analogue Input 1). Therefore, only analogue input channels not being used for a thermistor input can be connected to whilst using the S70-TP.
